Containment of a PSA has been achieved by entrapment within a scaffolding 3D hard mesh structure. The label sticks upon instant application of heat and pressure, which softens and deforms the mesh allowing for PSA release. The design eliminates the need for a release liner and release coating in labels offering a more sustainable product. Herein, the mesh reinforced PSA system was made by film formation of a binary polymer latex mixture consisting of ‘hard’ (high glass transition temperature, 𝑇𝑔,hard) polystyrene particles and a ‘soft’ (low glass transition temperature 𝑇𝑔,soft) poly(n-butyl acrylate)-based PSA latex of similar particle diameter, onto a model polyethylene terephthalate (PET) facestock. The system was annealed above 𝑇𝑔,h𝑎𝑟𝑑 to fuse the polystyrene colloids, creating a 3D interconnected open cellular network. The porous scaffold was shown by scanning electron microscopy and x-ray computed tomography. The linerless PSA label is in a dormant, ‘non-stick’ state at room temperature showing excellent blocking resistance at storage conditions. Adhesion is activated on demand with heat (𝑇 > 𝑇𝑔, hard) and light pressure. The adhesive behavior of the linerless PSA labels was probed using peel, shear strength and tack, its performance being promising.},\n bibtype = {article},\n author = {Brogden, Emily M. and Wilson, Paul F. and Hindmarsh, Steven and Hands-Portman, Ian and Unsworth, Andrew and Liarou, Evelina and Bon, Stefan A.

Both AAm and PEGDA were found to act as co-surfactants, resulting in the obtainment of monoliths with greater homogeneity in some cases. As a result these materials demonstrated significantly improved chromatographic performance for the separation of a standard mixture of proteins using reversed-phase liquid chromatography, in comparison to monoliths prepared with no internal phase monomer. In particular, the columns grafted with PEGDA were capable of separating a more complex mixture consisting of seven components. The inclusion of monomers in the internal phase also allowed for the functionalisation of the monoliths surface where the degree of polymerisation that occurred in the internal phase, which was governed by the monomer content in the internal phase and initiation location, determined whether polymeric chains or a hydrogel were grafted to the surface. A monolith grafted with AAm was also found to be capable of retaining polar analytes as a result of the increase in surface hydrophilicity.},\n bibtype = {article},\n author = {Desire, Christopher T. and Dario Arrua, R. and Mansour, Fotouh R. and Bon, Stefan A.

The amphiphilic macromonomers were synthesized by catalytic chain transfer emulsion polymerization (CCTP) and subsequent chain extension via sulfur-free reversible addition-fragmentation chain transfer (SF-RAFT). Their critical micelle concentration (CMC) was determined by dynamic light scattering (DLS), and micelle size was measured using DLS and small angle x-ray scattering (SAXS). The surface activity of the stabilizers was measured by pendant drop tensiometry and compared to modelled behaviour. For the mini-emulsion polymerizations, macromonomer stabilizers were added at a range of concentrations, with respect to the dispersed phase. Using less than 5 wt.% stabilizer, SEM micrographs showed many of the particles were bowl-shaped. This morphology was studied in depth and we propose that monomer transport occurs between particles during polymerization towards the smaller particles as a direct result of compartmentalization. At concentrations of 5 wt.% and higher, bimodal droplet and particle distributions were observed by DLS and SEM. We propose shear-dependent depletion flocculation as the explanation. Lastly, the effectiveness of the reactive stabilizers was tested in terms of latex stability and molecular weight control. Resistance to coagulation during freeze-thaw cycles and prolonged dialysis were tested. Examination of P(BzMA) reaction kinetics and molecular weight indicated that the incorporation of macromonomer is gradual and less than quantitative at the end of the polymerization process, in agreement with the mechanistic understanding.},\n bibtype = {article},\n author = {Booth, Joshua R. and Davies, Joshua D. and Bon, Stefan A.

The shape of the particles can be tuned from flower- to disk-like to spherical by elevating the polymerization temperature. The solvent environment also has a pronounced effect on the particle size. Time-resolved TEM reveals that the final particle morphology was formed in the early stages of the polymerization and that subsequent polymerization resulted in continued particle growth without affecting the morphology.

A temperature triggered response in the form of an upper critical solution temperature (UCST) type phase separation targeted near the freezing point of water manifests itself through light scattering as a clear-to-opaque transition. It is simultaneously amplified by an enhanced photoluminescence effect. The conceptual road sign application is a multi-lamellar flexible strip with an active layer of a polystyrene-based solution. The solvent is a plasticizer, here either dioctyl phthalate (DOP) or its alternative 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH). A collection of styrene-based macromolecules were made by free radical (co)polymerization, varying molecular weight and monomer feed composition. UCST-type phase diagrams for the polymer solutions were constructed from cloud point data measured with a bespoke photographic set-up, in which up to 30 samples were analyzed simultaneously monitoring both light scattering, in the form of opacity measurements, and fluorescence. For the latter, the concept of restricted motion enhanced photoluminescence, often referred to as aggregation-induced emission (AIE), was used. Polystyrene labelled with tetraphenylethylene (TPE) was used for this. The contrast between ‘ON’ and ‘OFF’ states in the conceptual ice warning signs was optimized by tuning the polymer concentration and the active layer thickness. Our prototype signs show full reversibility over many temperature cycles. We believe the concept can be of wider use in electricity-free signs and labels.},\n bibtype = {article},\n author = {Booth, Joshua R. and Young, Robert A. and Richards Gonzales, Andrés N. and Meakin, Zachary J. and Preuss-Weber, Corinna M. and Jaggers, Ross W. and Bon, Stefan A.

Such hiding pigments usually consist of non-absorbing, high refractive index nanoparticles, for example spherically shaped titanium dioxide nanopowders. However use of TiO2 carries a high environmental burden. To offset the carbon footprint and health concerns inherent with the use of titanium dioxide, one could approach the challenge of scattering optimization by modifying the morphology of the scattering elements rather than their refractive index. Here, inspired by the bright anisotropic scattering system found in nature, we demonstrate that anisotropic sphero-cylindrical particles can outperform the scattering efficiency of their isotropic counterparts - obtaining an excellent scattering performances across the visible electromagnetic spectrum. We developed a class of micron-sized scattering enhancers composed only of silica. We show that these cylindrical colloids are easily assembled into scattering supracolloidal balls, a new class of pigment microspheres which can be used in formulations for ultrabright coatings.},\n bibtype = {article},\n author = {Jacucci, Gianni and Longbottom, Brooke W and Parkins, Christopher C and Bon, Stefan A F and Vignolini, Silvia},\n journal = {J.

This binary mixture consists of a volatile solvent and non-volatile carrier oil. Crystallization is facilitated upon supersaturation due to evaporation of the volatile solvent. Microcapsule diameter can be easily tuned using microfluidics. This approach also proves to be scalable when using conventional mixers, yielding spikey microcapsules with diameters in the range of 10-50 µm.

Bacteria encapsulated inside biocoatings can perform useful functions, such as a biocatalyst in wastewater treatment. A biocoating needs to have high a permeability to allow a high rate of mass transfer for rehydration and the transport of both nutrients and metabolic products. It therefore requires an interconnected porous structure. Tuning the porosity architecture is a challenge. Here, we exploited rigid tubular nanoclays (halloysite) and non-toxic latex particles (with a relatively high glass transition temperature) as the colloidal “building blocks” to tailor the porosity inside biocoatings containing Escherichia coli bacteria as a model organism. Electron microscope images revealed inefficient packing of the rigid nanotubes and proved the existence of nanovoids along the halloysite/polymer interfaces. Single-cell observations using confocal laser scanning microscopy provided evidence for metabolic activity of the E. coli within the biocoatings through the expression of yellow fluorescent protein. A custom-built apparatus was used to measure the permeability of a fluorescein sodium salt in the biocoatings. Whereas there was no measurable permeability in a coating made from only latex particles, the permeability coefficient of the composite biocoatings increased with increasing halloysite content up to a value of 110-4 m h-1. The effects of this increase in permeability was demonstrated through a specially-developed resazurin reduction assay. Bacteria encapsulated in halloysite composite biocoatings had statistically significant higher metabolic activities in comparison to bacteria encapsulated in a non-optimized coating made from latex particles alone.},\n bibtype = {article},\n author = {Chen, Yuxiu and Krings, Simone and Booth, Joshua R. and Bon, Stefan A.

The macromonomers consisted of two blocks whose first was a random copolymer of methacrylic acid and methyl methacrylate, at 35:65 mol:mol, while the second block was n-butyl methacrylate P[(MAA-co-MMA)-block-PBMA]. The block copolymer colloids were disintegrated and micellized upon addition of ammonia. The resulting nano-sized polymer dispersions were used as reactive surfactants in the emulsion polymerization of n-butyl methacrylate. For this, a dual stage slow-fast monomer feed profile was used. The final polymer latexes were in the sub 100 nm range for particle diameter at 30 % w/w total polymer content. The emphasis of the work is to discuss and find an explanation for the observed particle size distributions in the three consecutive emulsion polymerization steps. The particle size distribution of the ω-unsaturated macromonomer latex synthesized by CCTP emulsion polymerization was found to be much broader than expected. This discrepancy is attributed to an extended particle nucleation period. The chain extension step in the macromonomer latex preparation showed considerable secondary nucleation. The presence of water soluble macromonomer species from the CCTP emulsion polymerization step assured that control of chain growth persisted. The use of the amphiphilic macromonomers as reactive surfactants in the form of a nanosized aggregate seed dispersion, showed that the average particle diameter could be tuned and that the molecular weight distributions could be regulated, when monomer starved conditions were used in the emulsion polymerizations.},\n bibtype = {article},\n author = {Lee, Wai Hin and Booth, Joshua R. and Bon, Stefan A.

It is specifically designed for systems where its value is substantially greater than 1. In these cases the classical Mayo equation and Gilbert’s chain length distribution (CLD) method fall short, in that the concentration ratio of chain transfer agent to monomer can no longer be assumed to be constant. Marked composition drift invalidates the use of both. In our proposed method we use the analytical concentration ratio of chain transfer agent to monomer (t = 0 s) and monomer conversion data, in combination with data for the cumulative molecular weight distributions as input. We determined an analytical solution for the cumulative weight distribution, which is used to calculate the cumulative number and chain length distributions. Chain transfer constants are found either by fitting the natural logarithmic chain length distribution (CLD) data at a given monomer conversion, or by plotting the fitted values for the slopes obtained from the natural logarithmic chain length distribution (CLD) data at a set degree of polymerization, as a function of monomer conversion. Our method is validated by analyses of molecular weight data obtained from Monte Carlo simulations. We used our methodology to determine an experimental value of ca. 223 as a chain transfer constant of n-dodecanethiol in vinyl acetate free radical polymerisation at 333.15 K, which we showed was in excellent agreement with the Smith method.},\n bibtype = {article},\n author = {Donald, Matt K and Bon, Stefan A.

The effect of the addition of salt, i.e. NaCl, on the emulsion polymerization is studied. It is shown that an increase in ionic strength of the dispersing medium in these polymerizations led to the formation of latexes of larger diameters. Along with an increase in size, the morphology of these polymer colloids changed from Janus to patchy with an increase in number of nanogels adsorbed on the polymer surface, as a function of the salt concentration in water. In particular, at the highest tested ionic strength, ca. 25 mM, fully armored polymeric particles surrounded by a dense layer of adsorbed stabilizing nanogels were formed. Kinetic studies carried out at varying NaCl concentrations suggested that particle formation in the reaction followed a combination of a coagulative nucleation mechanism, characterized by a clustering process of Janus precursors to form bigger aggregates, and droplet nucleation. Preliminary film formation studies on latexes made with n-butyl acrylate as comonomer indicated the potential of this technique for the production of coherent polymer films which included a substructure of functional nanogels.},\n bibtype = {article},\n author = {Lotierzo, Andrea and Meaney, Shane P. and Bon, Stefan A.

When low shear (300 rpm) was used for emulsification, the droplet and resulting void size distributions were observed to shift towards lower values when the emulsions were forced through capillaries of internal diameter less than 540 μm and all columns exhibited significant radial heterogeneity. When high shear was employed (14 000 rpm) the resulting emulsions preserved their structure when forced through these capillaries and possessed narrower void size distributions with no obvious radial heterogeneity observed upon curing.

Chemical crosslinking, involving the introduction of a water-soluble crosslinker, resulted in stronger chemical bonds between particles affording a rigid porous material known as a monolith. It was found that, in a simpler approach these materials could be prepared using a single latex where the addition of ammonium persulfate both resulted in the formation of the colloidal gel and initiated the crosslinking process. The pore size of the resulting monoliths was predictable as this was observed to directly correlate to the particle diameter, with larger pores achieved using particles of increased size. All gels obtained in this work were highly mouldable and retained their shape, which allowed for a range of formats to be easily prepared without the requirement of a mould.},\n bibtype = {article},\n author = {Desire, Christopher and Lotierzo, Andrea and Arrua, R.

The emulsification energy was increased, resulting in increased contact between emulsion droplets, allowing open cellular and highly interconnected structures to be achieved. This was coupled with a reduction in the internal phase volume allowing the obtainment of highly interconnected materials with excellent mechanical properties under compression, producing a Young’s modulus of 490 ± 90 MPa for a material with 36 ± 3% porosity. It was also found that the morphology of these materials could be altered through variations in the internal phase volume, the surfactant level and the emulsification energy.

The use of this class of RAFT-agents in heterogeneous polymerizations is however not trivial, because of their inherent low reactivity. In this work we demonstrate that two obstacles need to be overcome, one being control of chain-growth (propagation), the other monomer partitioning. Batch dispersion polymerizations of hydroxypropyl methacrylate in the presence of poly(glycerol methacrylate) macromonomers in water showed limited control of chain-growth. Semicontinuous experiments whereby monomer was fed improved results only to some extent. Control of propagation is essential for PISA to allow for dynamic rearrangement of colloidal structures. We tackled the problem of monomer partitioning (caused by uncontrolled particle nucleation) by starting the polymerization with an amphiphilic thermoresponsive diblock copolymer, already “phase...},\n bibtype = {article},\n author = {Lotierzo, Andrea and Schofield, Ryan M. and Bon, Stefan A.

Silver cations (Ag+) and the Ag+ chelator dithiothreitol (DTT) are used as signalling molecules. By exploiting their interplay, we conduct a series of ‘conversations’ between millimetre-sized beads. The communication process is monitored by tracking the response and behaviour of a central bead. This bead is loaded with the enzyme urease and has the ability to undergo a change in colour associated with a change in pH. Competitive communication between three beads, whereby the central bead receives two competing signals from two senders, is shown. We believe that our hydrogel-based system demonstrates an advance in the communication capabilities of small soft matter objects.},\n bibtype = {article},\n author = {Jaggers, Ross W and Bon, Stefan A F},\n doi = {10.1039/C7TB02278F},\n journal = {J.

All three oils were epoxidized to give renewable epoxy monomers containing between 3.8 and 4.7 epoxides per molecule. Polymerisation was achieved with cyclic anhydrides catalysed by 4-methyl imidazole at 170 and 210 °C. Polymers produced from methyl tetrahydrophthalic anhydride (Aradur917®) had greater tensile strength and Young’s Modulus (tensile strength = 12.8 MPa, Young’s Modulus = 1005 MPa for grapeseed) than methyl nadic anhydride (MNA) derived materials (5.6 and 468 MPa for grapeseed) due to increased volume of MNA decreasing crosslink density. Soybean and grapeseed oils produced materials with higher tensile strength (5.6–29.3 MPa) than rapeseed derived polyesters (2.5–3.9 MPa) due to a higher epoxide functionality increasing crosslinking. Tg’s of the polyesters ranged from −36 to 62 °C and mirrored the trend in epoxide functionality with grapeseed producing higher Tg polymers (−17 to 17 °C) than soybean (−25 to 6 °C) and rapeseed (−36 to −27 °C). Grapeseed oil showed similar properties to soybean oil in terms of Tg, thermal degradation and Young’s Modulus but produced polymers of lower tensile strength. Therefore grapeseed oil would only be a viable substitute for soybean for low stress applications or where thermal properties are more important.},\n bibtype = {article},\n author = {Clark, A.

The process consists of straightforward steps: 1. Preparation of a bi-composite colloidal sol i.e. polymer particles + inorganic particles dispersed in a liquid, 2. Drying of the mixture onto a suitable hard substrate, 3. Heating the dried film above the glass transition temperature of the polymer, and 4. Re-dispersion and chemical etching of the inorganic medium. The primary driver is capillary imbibition of the polymer melt into the inorganic colloidal template. 2D particle tracking probes the diffusional behaviour of the roughened objects in comparison with their smooth precursors. We show that, despite large scale roughness (up to 10 % asperity size with respect to particle diameter), Stokes law is obeyed and the particles motion can be modelled simply with the Einstein-Stokes-Sutherland relation.},\n bibtype = {article},\n author = {Longbottom, Brooke W and Somuncuoglu, Birsen and Punter, Jacob and Longbottom, Sarah and Bon, Stefan A F},\n doi = {10.1039/C7SM00589J},\n journal = {Soft Matter}\n}

We utilize the enzyme urease to programme a self-regulated change in pH, which in turn activates the designed response of gel fibre disintegration or a change in gel bead colour. This design allows for independent response behaviour of a collection of bodies in a single closed system, as well as inter-material communication on shorter length scales. The incorporation of responsive time control directly into soft matter objects demonstrates an advance in the field of autonomous materials.},\n bibtype = {article},\n author = {Jaggers, Ross W. and Bon, Stefan A.

A mechanistic understanding of the polymerization process is limited which restricts the use of the technique in the fabrication of more complex, multilayered colloids. In this paper clarity is provided through an in-depth investigation into the Pickering emulsion polymerization of methyl methacrylate (MMA) in the presence of nano-sized colloidal silica (Ludox TM-40). Mechanistic insights are discussed by studying both the adsorption of the stabiliser at the surface of the latex particles and polymerization kinetics. The adhesion of the Pickering nanoparticles was found not to be spontaneous, as confirmed by cryo-TEM analysis of MMA droplets in water and monomer-swollen PMMA latexes. This supports the theory that the inorganic particles are driven towards the interface as a result of a heterocoagulation event in the water phase with a growing oligoradical. The emulsion polymerizations were monitored by reaction calorimetry in order to establish accurate values for monomer conversion and the overall rate of polymerizations (RP). RP increased for higher initial silica concentrations and the polymerizations were found to follow pseudo-bulk kinetics},\n bibtype = {article},\n author = {Lotierzo, Andrea and Bon, Stefan A F},\n doi = {10.1039/C7PY00308K},\n journal = {Polymer Chemistry}\n}

The water phase consisted of the monomers acrylamide (AM) and N,N'-methylenebisacrylamide (MBAM), an initiator as well as the amphiphilic macro-RAFT agent, that is 2-(butylthiocarbonothioylthio)-2-poly(n-butyl acrylate)-b-poly(acrylic acid), which was used as an anionic polymeric surfactant. The presence of these amphiphilic species allowed the successful preparation of a polyHIPE upon polymerization. The effect of concentration of macro-RAFT agent, pH, initiator, hexadecane as an organic modifier and the polymerization temperature on the morphology of the resulting porous materials was investigated. Varying the lengths of the hydrophilic and hydrophobic blocks of the macro-RAFT agent resulted in polyHIPEs with different porous structures. The presence of RAFT functionality in the polyHIPE was confirmed by elemental analysis, EDX-SEM, Raman and FT-IR spectroscopies. Raman mapping revealed full coverage of the void walls with dithiocarbamate groups.},\n bibtype = {article},\n author = {Khodabandeh, Aminreza and Arrua, R.

If the balance of properties, performance and process requirements are achieved this may lead to HVDC insulation systems and equipment having a reduced footprint, larger power densities, and greater multi-stress resilience with longer service lifetimes. It reports findings of a project that is engaging this challenge and investigates the development and scaling of new thermoset based nanocomposite electrical insulation materials for HVDC power transmission applications. Some of the results such as increased electrical breakdown strength and reduced electrical conductivity for reactively surface functionalised nanosilica, and increased thermal conductivity for nano boron nitride and their significance in regard to the wider application of these electrical insulation materials are also discussed.

The book first introduces the basic concepts and principles of colloidal particles at liquid-liquid interfaces including the interactions and conformations. The book then discusses the latest advances in emulsions and bicontinuous emulsions stabilized by both solid and soft particles and finally the book covers applications in food science and oil extraction.With contributions from leading experts in these fields, this book will provide a background to academic researchers, engineers, and graduate students in chemistry, physics and materials science.

The stimuli-responsive behavior of these nanoparticles with a poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) hemicorona is investigated. The synthesis is based on a modified version of the Pickering emulsion polymerization technique in combination with surface-initiated atom transfer radical polymerization (ATRP) in a "grafting from" approach. In a first step, poly(vinyl acetate) (PVAc) latex particles are prepared via Pickering emulsion polymerization. Colloidal stability is provided by 30 nm silica nanoparticles that adhere to the surface of the growing polymer particles. This results in polymer latexes which are armored with a layer of tightly immobilized nanoparticles, one side of which is immersed in the polymer particle and thus protected. After modification of the exposed side of the particles through chemisorption of an ATRP initiator, that is (2-bromo-2-methyl)propionyl-oxyhexyltriethoxysilane, and the removal of the particles from the interface, PDMAEMA chains are grown from this modified side of the silica particles, yielding well-defined Janus nanoparticles with a stimuli-responsive PDMAEMA hemicorona. Transmission and scanning electron microscopy, dynamic light scattering, thermogravimetric analysis and turbidity measurements were used to characterize the Janus particles. Most importantly, this synthetic approach is easily scalable and can be amended to furnish a wide range of nanoscale hybrid Janus particles. Furthermore, we demonstrate reversible switching behavior upon pH and temperature changes and find a peculiar self-assembly behavior of the Janus particles into linear strings at low pH and high concentration.},\n bibtype = {article},\n author = {Ruhland, Thomas M. and McKenzie, Holly S. and Skelhon, Thomas S. and Bon, Stefan A F and Walther, Andreas and M??ller, Axel H E},\n doi = {10.1016/j.polymer.2015.10.022},\n journal = {Polymer}\n}

We present a user-friendly computational model that can be used to determine equilibrium orientations and the adhesion energy of colloidal particles at interfaces. The model determines the free energy profile of particle adsorption at liquid-liquid interfaces using a triangular tessellation scheme. We demonstrate the use of the model, using a variety of anisotropic particles and demonstrate its ability to predict and explain experimental observations of particle behaviour at interfaces. In particular, we show that the concept of hydrophilic lipophilic balance commonly applied to molecular surfactants is insufficient to explain the complexity of the activity of colloidal particles at interfaces. In addition, we show the importance of the knowledge of the free energy adsorption profile of single particles at interfaces and the impact on overall free energy of emulsification of packed ensembles of particles. The delicate balance between optimization of adhesion energy, adsorption dynamics and particle packing is shown to be of great importance in the formation of thermodynamically stable emulsions. In order to use the model, the code is implemented by freely available software that can be readily deployed on personal computers.},\n bibtype = {article},\n author = {Ballard, Nicholas and Bon, Stefan A F},\n doi = {10.1016/j.jcis.2015.02.069},\n journal = {Journal of Colloid and Interface Science}\n}

The particles are made by seeded dispersion polymerization of butyl acrylate in the presence of poly(styrene) seed particles. Surface nucleation by capture of the oligoradicals onto the surface of the seed particles thereby forming a distinct new polymer phase is found to be the formation mechanism of these particles.

The microgels were synthesized by precipitation polymerization in water. Due to the water-soluble nature of the MH monomer, the VPTT at which the microgel particles contract shifts to higher values by increasing the incorporated amounts of methacryloyl hydrazide from 0 to 5.0 mol %. The VPTT of the copolymer microgel dispersions in water can be fine-tuned upon addition of hydrophobic/hydrophilic aldehydes, which react with the hydrazide moiety to produce the hydrazone analogue. This hydrazone formation is reversible, which allows for flexible, dynamic control of the thermo-responsive behavior of the microgels. The ability to switch the VPTT was demonstrated by exposing hydrophilic streptomycin sulfate salt incubated microgel particles to an excess of a hydrophobic aldehyde, that is benzaldehyde. The temperature at which these microgels contracted in size upon heating was markedly lowered in these aldehyde exchange experiments. Transformation into benzaldehyde hydrazone derivatives led to assembly of the microgel particles into small colloidal clusters at elevated temperatures. This control of supracolloidal cluster formation was also demonstrated with polystyrene particles which had a hydrazide functionalised microgel shell. (c) 2014 Wiley Periodicals, Inc. J. Polym.

Here we demonstrate the synthesis of non-covalently crosslinked nanogel particles in which the crosslinking through covalent bonds is replaced by physical crosslinking induced by strong self-complementary quadruple hydrogen bond interactions. The multiple hydrogen bond (MHB) arrays were introduced in the form of a 2-ureido4[1H]pyrimidinone (UPy) functionalized polyethylene glycol methacrylate (PEGMA) comonomer, which was employed in the synthesis of colloidal nanogels made from N-isopropylacrylamide (NIPAm) or a mixture of 2-(2-methoxyethoxy) ethyl methacrylate and oligo(ethylene glycol) methacrylate (MEO(2)MA-co-OEGMA) following conventional free radical polymerization routes.

The morphology of the films obtained for these two different scenarios was similar and resembled a honeycomb structure. However, their water-resistance properties differed drastically.

Upon swelling, the polymersomes lose their original simple bilayer morphology and transform into more complex coil-like and patchy colloidal structures, as investigated experimentally by cryogenic electron microscopy (cryo-EM). Dissipative particle dynamics (DPD) simulations on a model flat bilayer indeed show that transitions can occur upon bilayer swelling, which is accompanied by a change in the mechanical bilayer properties. The transition involves the formation of water pockets in the interior regions of the bilayer. Co-existence of the various morphologies in the experiments suggests an activation barrier towards morphological changes and a possibility of multiple meta-stable states. The latter indeed is supported by the existence of multiple minima in the surface tension as a function of bilayer area, as found in the simulations.},\n bibtype = {article},\n author = {Parmenter, Christopher D.

In this work we combine simulations and experiments to investigate the behaviour of an isolated microscopic hematite particle of superellipsoidal shape. We show that this microparticle can adopt one of three orientations when adhered to a hexadecane–water interface. Two of the orientations, and estimates for their relative populations, could be assigned to two thermodynamic minima on the energy landscape as generated through both free-energy minimization and particle trajectory simulations. The third orientation was found to correspond to a kinetically trapped state, existing on certain particle trajectories in a region of a negligible gradient in free energy. To underpin the simulations the individual orientation of a set of 100 isolated particles was explored by means of scanning electron microscopy (SEM) using the gel trapping technique as a tool. Atomic force microscopy (AFM) was additionally used to support the experimental findings. This is the first example of such a kinetic metastable state being observed for particles at liquid–liquid interfaces.},\n bibtype = {article},\n author = {Morgan, Adam R. and Ballard, Nicholas and Rochford, Luke A. and Nurumbetov, Gabit and Skelhon, Thomas S. and Bon, Stefan A.

It was found by cryo-TEM analysis that the hybrid dispersions were a mixture of colloidal particles composed of a small fraction of free montmorillonite clay platelets, polymer latex particles, polymer particles to which one or more clay platelets where adhered onto its surface and a fraction of colloidal material consisted of a clay platelet with a polymer lob adhered to either side, in other words hybrid particles with a dumbbell-like morphology. The films made from these waterborne hybrid dispersions presented a homogeneous dispersion of the clay platelets and exfoliated morphology. The shear adhesion failure temperature (SAFT) and shear resistance of the hybrid latex films synthesized with CMA16 were better than those prepared with a commercial clay (Cloisite 30B), but presented a liquid-like probe-tack performance. When allyl methacrylate (AMA) was added in the formulation, SAFT and shear resistance improved, but the film had a very low energy of adhesion due to the excessively crosslinked matrix. In order to reduce crosslink density and thus improve the adhesion energy, small amounts of chain transfer agent, in this case n-dodecyl mercaptan (n-DDM), were used in the miniemulsion polymerization process. Adhesive films made from these waterborne hybrid dispersions showed excellent SAFT and shear resistance, and good energy of adhesion.},\n bibtype = {article},\n author = {Bonnefond, Audrey and Mičušík, Matej and Paulis, Maria and Leiza, Jose R. and Teixeira, Roberto F A and Bon, Stefan A F},\n doi = {10.1007/s00396-012-2649-3},\n journal = {Colloid and Polymer Science},\n number = {1}\n}

Up to 50 wt% of the fat content in chocolate, that is cocoa butter and milk fats, is replaced with fruit juice in the form of emulsion droplets using a quiescent Pickering emulsion fabrication strategy. Fumed silica particles are used in combination with chitosan under acidic conditions (pH 3.2-3.8) to prepare water-in-oil emulsions, the oil phase being sunflower oil, molten cocoa butter, and ultimately white, milk, and dark chocolate. Adsorption of the polycationic chitosan molecules onto the surface of the silica particles influenced the particle wettability making it an effective Pickering stabilizer, as shown by cryogenic scanning electron microscopy analysis. The formation of a colloidal gel in the continuous (molten) oil phase provided the system with a yield stress, hereby giving it a gel-like and thus quiescent behaviour under low shear conditions, as determined by rheological measurements. This warrants a homogeneous distribution of emulsion droplets as settling through gravity upon storage under molten/liquid conditions is arrested. In our low-fat chocolate formulations the cocoa butter has the desired polymorph V structure, and neither sugar nor fat bloom was observed upon storage of the fruit juice containing chocolate confectionaries.

The average size of the capsules is 140. nm and 119. nm, respectively. The chemical structure of the sample was analyzed using Fourier Transformed Infrared Spectroscopy (FTIR). Crystallography of nanocapsules was investigated by X-ray diffractometer. The surface morphology was studied by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The thermal properties and thermal stability of the sample were obtained from Differential Scanning Calorimeter (DSC) and Thermal Gravimetric Analysis (TGA). The temperatures and latent heats of melting and crystallizing of PEMA nanocapsule were determined as 32.7 and 29.8 ??C, 198.5 and -197.1. kJ/kg, respectively. TGA analysis indicated that PEMA/octadecane nanocapsule had good thermal stability. The nanocapsules prepared in this work had a much higher encapsulation ratio (89.5%) and encapsulation efficiency (89.5%). Therefore, the findings of the work lead to the conclusion that the present work provides a novel method for fabricating nanoencapsulated phase change material, and it has a better potential for thermal energy storage. ?? 2012 Elsevier Ltd.},\n bibtype = {article},\n author = {Zhang, G.

The cellular polymer films exhibit impressive physical and mechanical properties.

Laponite clay XLS is used as stabilizer in the Pickering emulsion polymerization of a variety of monomer mixtures, that is, methyl methacrylate and n-butyl acrylate, styrene and n-butyl acrylate, and styrene and 2-ethylhexyl acrylate. Overall solids contents of the hybrid latexes in complete absence of coagulation of up to 24 wt % are reported under batch conditions. Key mechanistic aspects of the Pickering emulsion polymerization process are discussed. The use of monomers that have high water solubility and are prone to hydrolyze under basic conditions, for example methyl methacrylate, should be restricted. The use of small amounts of methacrylic acid as auxiliary monomer promotes clay adhesion to the surface of the particles in the Pickering emulsion (co)polymerization of hydrophobic monomers. Detailed kinetic studies at both 60 and 80 °C of the Pickering emulsion copolymerization of styrene and n-butyl acrylate (Sty:BA = 0.67 w/w) are reported, with varying amounts of Pickering stabilizer. The Laponite clay discs play a crucial role in the particle formation (nucleation) stage of the Pickering emulsion polymerization process. Use of increasing amounts leads to smaller average particle sizes but inflicts longer nucleation periods, thereby broadening the particle size distributions. We report the occurrence of a catastrophic coagulation phenomenon for Pickering emulsion polymerizations carried out at a low initiator (ammonium persulfate) flux at 60 °C, for a small window of concentrations of Laponite clay discs.},\n bibtype = {article},\n author = {Teixeira, Roberto F A and McKenzie, Holly S. and Boyd, Ashton A. and Bon, Stefan A F},\n doi = {10.1021/ma201691u},\n journal = {Macromolecules},\n number = {18}\n}

First, will discuss the phe- nomenon of heterocoagulation and its various driving forces, such as electrostatic interactions, the hydrophobic effect, and secondary molecular interactions.We will then address methods that involve assembly of nanoparticles onto or around the more liquid precursors (i.e., swollen/growing latex particles or monomer droplets). We will focus on the phenomenon of Pickering stabilization.We will then discuss features of particle interaction with soft interfaces, and see how the adhesion of particles onto emulsion droplets can be applied in suspension, miniemulsion, and emulsion polymerization.

The developed method to quantify the number of silica nanoparticles in the water phase proved to be an invaluable tool for determining key features of the polymerization process.

Droplets were generated in a coflow device from a water-in-oil high internal phase emulsion (HIPE), hereby creating a water-in-oil-water (W/O/W) emulsion, The individual droplets of monomer HIPE were polymerized downstream in the channel through photopolymerization. The polymer particles produced via this strategy possess very large macropores in comparison with the more conventional porous polymer beads synthesized by inducing in situ phase separation throughout the polymerization process through the use of porogenic solvents. Epoxy-functionalized Porous particles made using the HIPE microfluidic method showed superior performance in consecutive azide and cycloaddition "click"-"click" modification procedure monitored by IR. Our microfluidic approach led to the successful miniaturization of monodisperse submillimeter spherical poly(HIPE) beads, down to diameters of 400 mu m. More strikingly is the production of poly(HIPE) rods, which were obtained by using a Viscous HIPE, which in coflow emulsification formed an unstable jet that broke up into rodlike sections. These rodlike droplets maintained their shapes throughout the microfluidic channel and did not relax back into spherical droplets, allowing for production of poly(HIPE) rods upon photopolymerization. The nonspherical shape in this case is not determined by confined channel geometries, which to the best Of Our knowledge is unprecedented as a strategy to produce nonspherical polymer particles with microfluidics.},\n bibtype = {article},\n author = {Gokmen, M.

Here, polymer particles having Laponite clay armor were prepared by the Pickering miniemulsion polymerization of n-lauryl acrylate. The resulting "soft-hard'' poly(lauryl acrylate) (PLA) -Laponite hybrid particles were blended at various low concentrations with a standard poly(butyl acrylate-co-acrylic acid) (PBA) latex for application as a waterborne pressure-sensitive adhesive (PSA). The tack adhesion properties of the resulting nanocomposite films were compared with the performance of the PBA when blended with either a conventional non-armored PLA latex, with Laponite RD nanosized clay discs, or a mixture of both. A true synergistic effect was discovered showing that the clay-armored supracolloidal structure of the hybrid particles was essential to achieve a superior balance of viscoelastic properties. The addition of small amounts, e. g. 2.7 wt%, of the "soft-hard'' clay-armored PLA particles increased the tack adhesion energy considerably more than found for the two individual components or for the sum of their individual contributions. The soft PLA core ensures that the adhesives are not stiffened too much by the nanosized Laponite clay. Slippage at the interface between the nanoclay platelets and the PBA matrix introduces an additional energy dissipation mechanism during deformation. Through the synergistic effect of the clay and PLA in the supracolloidal armored latex structure, the tack adhesion energy is increased by 45 J m(-2), which is about 70% greater than found for the PBA adhesive alone.},\n bibtype = {article},\n author = {Wang, Tao and Colver, Patrick J. and Bon, Stefan Antonius Franciscus and Keddie, Joseph L.},\n doi = {10.1039/b904740a},\n journal = {Soft Matter},\n number = {20}\n}

Lower particle concentrations result in droplet coalescence 11 whereas an excess of particles in the system leads to their undesired loss and in principle, can affect the properties of the material derived from the Pickering emulsions. For a particular system, the concentration of particles required for the efficient stabilization of droplets depends on many factors, including the ratio between the dimensions of droplets and particles, and the number of particles. 9 Current methods for producing particle-coated emulsions generate droplets with a broad distribution of sizes, which complicates the rationalization of the amount of particles introduced in the system. Recently, microfluidic emulsi-fication has provided a means for the formation of highly mono-disperse droplets. 12,13 Furthermore, Subramaniam et al. 14 have shown that the deposition of microbeads from the continuous phase to the bubble-liquid interface is greatly assisted by hydrodynamic flow. Herein, we describe a microfluidic " inside-out " approach to the generation of monodisperse water-in-oil and oil-in-water Pickering emulsions, as well as the supracolloidal polymer microspheres. Our strategy has the following new features: the microfluidic emulsifica-tion of a dispersion of colloidal particles in the particle-free continuous phase and a rationalized, based on geometric consid-erations, approach to controlling the coverage of the droplets with a layer of solid particles. Emulsification was conducted in a microfluidic flow-focusing droplet generator. 13 A dispersion of 3.5 µm-diameter poly(divinyl-benzene-methacrylic acid) (poly(DVB-MAA)) particles in the water-ethanol (85/15 v/v) mixture was emulsified in hexadecane. The value of θ between the polymer film derived from the particles and the water-ethanol mixture was 82.2 (2.1°. Upon the formation of droplets with polydispersity below 5%, the microbeads rapidly migrated from the interior of the droplets to the droplet surface. Since the diameter of the particles used in the present work was significantly smaller than the diameter of the droplets, the surface coverage of the droplets, δ, was estimated as δ) A p /A d) C p F d a d / (4F p a p) (eq 1), where A d and A p are the surface area of the droplet and the area of the droplet coated with particles, respectively; F d is the density of the droplet phase, and C p and F p are the concentration and the density of particles, respectively. In Figure 1 the broken line shows the estimated variation in the concentration of particles required to achieve complete coverage of the droplets with varying size with a colloidal monolayer, with the assumptions that (i) all particles migrate from the droplet interior to the droplet surface and (ii) at the interface the particles form a hexagonal lattice with a packing density of 0.906. Below the line, the amount of particles is not sufficient for the complete coverage of the droplets; whereas above the line, the microbeads present in excess form a multilayer shell or remain in the droplet interior. Since the number of particles is proportional to the droplet volume (∼a d 3) and A d ≈ a d 2 , complete coverage of droplets with larger radii requires a lower concentration of the particles. In the experiments, we controlled the surface coverage of the droplets by varying independently the value of C p from 4 to 16 wt % and the values of a d from 40 to 100 µm (by tuning the ratio of flow rates of the droplet-to-continuous phases. 14 Filled symbols in Figure 1 show the experimental results. Droplets with δ g 0.7 were stable to coalescence, whereas droplets with δ < 0.7 were prone to coalescence when collected at the exit of the microfluidic droplet generator. The attachment of particles from the droplet phase to the liquid-liquid interface and the formation of the close-packed crystalline shell occurred within several seconds and was assisted by the hydrodynamic flow. 14 Owing to the very rapid particle jamming at the fluid interface, at high values of C p , we were able},\n bibtype = {article},\n author = {Nie, Zhihong and Jai, Il Park and Li, Wei and Bon, Stefan A F and Kumacheva, Eugenia},\n doi = {10.1021/ja807764m},\n journal = {Journal of the American Chemical Society},\n number = {49}\n}

\n Particle-stabilized emulsions (Pickering emulsions) have recently seen a surge in interest, owing to their extremely high stability against coalescence and a broad range of applications in the fabrication of functional materials, for example, hollow permeable structures, 1 foams, 2,3 and hybrid supracolloidal assemblies. 4-6 Adsorption of colloidal particles to liquid-liquid interfaces occurs when they are not completely wetted by any of the phases. The attachment of a particle of radius a p to a water-oil interface is governed by a reduction of surface energy, E) πa p 2 γ(1 -|cos θ|) 2 , where γ is the interfacial tension between the two liquid phases and θ is the contact angle of the particle at the fluid interface. 7-10 Pickering emulsions are generated by injection methods or by the shearing of a mixture of two immiscible fluids with the solid particles present in excess, that is, in an amount that is significantly larger than is required for the complete coverage and stabilization of the droplets.

For a particular system, the concentration of particles required for the efficient stabilization of droplets depends on many factors, including the ratio between the dimensions of droplets and particles, and the number of particles. 9 Current methods for producing particle-coated emulsions generate droplets with a broad distribution of sizes, which complicates the rationalization of the amount of particles introduced in the system. Recently, microfluidic emulsi-fication has provided a means for the formation of highly mono-disperse droplets. 12,13 Furthermore, Subramaniam et al. 14 have shown that the deposition of microbeads from the continuous phase to the bubble-liquid interface is greatly assisted by hydrodynamic flow. Herein, we describe a microfluidic \" inside-out \" approach to the generation of monodisperse water-in-oil and oil-in-water Pickering emulsions, as well as the supracolloidal polymer microspheres. Our strategy has the following new features: the microfluidic emulsifica-tion of a dispersion of colloidal particles in the particle-free continuous phase and a rationalized, based on geometric consid-erations, approach to controlling the coverage of the droplets with a layer of solid particles. Emulsification was conducted in a microfluidic flow-focusing droplet generator. 13 A dispersion of 3.5 µm-diameter poly(divinyl-benzene-methacrylic acid) (poly(DVB-MAA)) particles in the water-ethanol (85/15 v/v) mixture was emulsified in hexadecane. The value of θ between the polymer film derived from the particles and the water-ethanol mixture was 82.2 (2.1°. Upon the formation of droplets with polydispersity below 5%, the microbeads rapidly migrated from the interior of the droplets to the droplet surface. Since the diameter of the particles used in the present work was significantly smaller than the diameter of the droplets, the surface coverage of the droplets, δ, was estimated as δ) A p /A d) C p F d a d / (4F p a p) (eq 1), where A d and A p are the surface area of the droplet and the area of the droplet coated with particles, respectively; F d is the density of the droplet phase, and C p and F p are the concentration and the density of particles, respectively. In Figure 1 the broken line shows the estimated variation in the concentration of particles required to achieve complete coverage of the droplets with varying size with a colloidal monolayer, with the assumptions that (i) all particles migrate from the droplet interior to the droplet surface and (ii) at the interface the particles form a hexagonal lattice with a packing density of 0.906. Below the line, the amount of particles is not sufficient for the complete coverage of the droplets; whereas above the line, the microbeads present in excess form a multilayer shell or remain in the droplet interior. Since the number of particles is proportional to the droplet volume (∼a d 3) and A d ≈ a d 2 , complete coverage of droplets with larger radii requires a lower concentration of the particles. In the experiments, we controlled the surface coverage of the droplets by varying independently the value of C p from 4 to 16 wt % and the values of a d from 40 to 100 µm (by tuning the ratio of flow rates of the droplet-to-continuous phases. 14 Filled symbols in Figure 1 show the experimental results. Droplets with δ g 0.7 were stable to coalescence, whereas droplets with δ < 0.7 were prone to coalescence when collected at the exit of the microfluidic droplet generator. The attachment of particles from the droplet phase to the liquid-liquid interface and the formation of the close-packed crystalline shell occurred within several seconds and was assisted by the hydrodynamic flow. 14 Owing to the very rapid particle jamming at the fluid interface, at high values of C p , we were able\n

Free radical polymerizations are carried out using a variety of hydrophobic monomers (i.e., styrene, lauryl (meth)acrylate, butyl (meth)acrylate, octyl acrylate, and 2-ethyl hexyl acrylate). Armored latexes, of which the surfaces of the particles are covered with clay discs, are obtained, as confirmed by scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM). Overall polymerization kinetics of the Pickering miniemulsion polymerizations of styrene were investigated via gravimetry. Comparison with the bulk polymerization analogue clearly shows compartmentalization. Moreover, retardation effects up to intermediate monomer conversions are observed; they are more prominent for the smaller particles and are ascribed to the Laponite clay. A model is presented that allows for the prediction of the average particle size of the latexes produced as a function of the amounts of monomer and Pickering stabilizers used. It shows that under specific generic conditions the number of clay discs used correlates in a linear fashion with the total surface area of the latex particles. This is a direct result of the reversibility of the Laponite clay disc adhesion process under the emulsification conditions (i.e., sonication) used.},\n bibtype = {article},\n author = {Bon, Stefan A.F. and Colver, Patrick J.},\n doi = {10.1021/la701150q},\n journal = {Langmuir},\n number = {16}\n}

It has been shown that macromonomers of low molar mass can be synthesised with an apparent chain transfer constant, C-S(E), of ca. 1300 down to a threshold value of Ca. 20 ppm of CoBF. Below this value an initial 20% shot of monomer/catalyst mixture was necessary to prevent events involved in the catalytic chain transfer process becoming diffusion controlled and to prevent the reaction to proceed under monomer starved conditions. Analysis of the Co(II) species by SQUID has been carried out. CoBF shows a value for its effective magnetic susceptibility of 1.77 mu (B). It was found that a correction for the response of the sample container is essential for reliable data to be achieved. Diffusion ordered 2D-NMR spectroscopy (DOSY) has been used as a method to study the catalyst diffusion dependence for the rate coefficient of chain transfer. However, the apparent values of the found diffusion coefficients are an order of magnitude above the natural limit for center of mass diffusion.},\n bibtype = {article},\n author = {Bon, Stefan A.F. and Morsley, David R. and Waterson, Jennifer and Haddleton, David M. and Lees, Martin R. and Horne, Tim},\n doi = {10.1002/1521-3900(200103)165:1<29::AID-MASY29>3.0.CO;2-5},\n journal = {Macromolecular Symposia},\n number = {1}\n}

Use of a batch reaction leads to hydrolysis of catalyst, a mixture of mechanisms and poor control of the reaction. A feed process is described that adds catalyst as a solution in monomer over the course of the reaction. The feed process is applied to a range of monomers of methacrylic acid (2), 2-aminoethyl methacrylate hydrochloride (3), 2-hydroxyethyl methacrylate (4), 2-methacryloxyethyl phosphoryl choline (5), glycerol monomethyl methacrylate (6), and 3-O-methacryloyl-1,2:5,6-di-O-isopropylidene-D-glucofuranose (7). Use of the feed process for water-soluble monomers in conjunction with 1 as a catalytic chain-transfer agent gives high-conversion, > 90%, water-soluble macromonomers. The number-average molecular mass (Mn was determined by integration of the 1H NMR spectrum comparing the vinylic end group with the remainder of the backbone. Pseudo-Mayo plots were constructed by measuring the Mn at high conversion as a function of [monomer]/[catalyst] to give observed chain-transfer constants of 1120, 958, and 1058 for 4, 6, and 2, respectively.

Living radical polymerisation involving nitroxide stabilised radicals, transition metal mediated and reversible addition fragmentation (RAFT) is covered. This overview is followed by some specific examples of the use of copper(I) mediated living radical polymerisation for the synthesis of some water soluble/dispersible polymers. Firstly the use of a modified SPAN surfactant to polymerise 2-(dimethylamino)ethyl methacrylate (DMAEMA) producing polymers with narrow polydispersity and controlled Mn is described (Mn = 6700, PDI = 1.27). These polymers disperse in acidic aqueous media with a CAC of 0.16 gL-1. Derivatised solketal is described as an initator for sequential atom transfer polymerisation of methyl methacrylate (MMA) and DMAEMA to give Y-shaped water soluble polymers. These two examples serve to illustrate the range of topology and hydrophilic functionality which can easily be incorporated into vinyl polymers through living radical methodology.},\n bibtype = {inbook},\n author = {Bon, Stefan A.F. and Ohno, Kohji and Haddleton, David M.},\n doi = {10.1021/bk-2001-0780.ch009},\n chapter = {Water-Soluble and Water Dispersible Polymers by Living Radical Polymerisation},\n title = {ACS Symposium Series (vol 780)}\n}

The molecular weight distributions have been found to be different from those obtained by SEC, with the MALDI spectra underestimating the contribution of the higher mass macromolecules leading to an underestimation of the average molecular weights. Three distributions are observed in the mass spectra that correspond to the initiation and interchain-exchange mechanisms producing three different macromolecular species. The pre-dominant species is an integral sum of the repeat unit indicating that anionic ring-opening propagation is fast when compared to intermolecular chain transfer. This is in conflict with earlier studies and indicates that the relative rates of transfer by different processes are highly dependent upon reaction conditions.},\n bibtype = {article},\n author = {Haddleton, David M and Bon, Stefan A F and Robinson, Kay L and Emery, N Julian and Moss, Ian},\n doi = {10.1002/(SICI)1521-3935(20000301)201:6<694::AID-MACP694>3.0.CO;2-I},\n journal = {Macromolecular Chemistry and Physics},\n number = {6}\n}

Both the nitroxides (plus DTBPO as a radical source) and alkoxyamines were investigated in the controlled radical polymerization (CRP) of styrene, and their behavior was compared to that of TEMPO. Polymerization mediated by each nitroxide display a linear relationship between molecular weight and conversion, producing material of low polydispersity indicating a controlled process. However, a comparison of kinetic behavior was complicated by the unknown concentration of active species present. Polymerizations with preformed alkoxyamines at a known concentration also displayed controlled behavior (polydispersities 1.25-1.5), and an influence of nitroxide substituent on the overall rate of polymerization could be determined. PROXYL and the dimethylaniline-substituted nitroxide gave similar CRP rates to TEMPO, whereas a Ph or (to a lesser extent) p-CF3Ph substituent resulted in significantly faster reactions. These results are discessed in terms of the likely steric and electronic influence of substituents on the nitroxide radical center, and the resulting influence on polymerization rate. It is concluded that the steric bulk of the Ph substituent is the most likely cause of the rate enhancement displayed by the corresponding mediator.},\n bibtype = {article},\n author = {Cameron, N R and Reid, a J and Span, P and Bon, S a F and Steven van Es, J J G and German, a L},\n doi = {10.1002/1521-3935(20001101)201:17<2510::AID-MACP2510>3.3.CO;2-J},\n journal = {Macromol.

Method 1 involves the homolysis of the -COBr bond with a subsequent reaction, via coupling or disproportionation, with an external radical species. The reaction with 2,2,6,6-tetramethylpiperidin-N-oxyl shows a high conversion (78%) of the -bromoPMMAchains into their corresponding macromonomer analogues. Method 2 utilizes monomers that are able to undergo radical addition followed by subsequent fragmentation. Reactions with trimethyl[1-(trimethylsiloxy)phenylethenyloxy]silane and allyl bromide show quantitative and 57% transformation, respectively. Method 3 is the reaction of a monomer that yields a relatively more stable secondary, or primary, carbon–halogen bond. Reactions with divinylbenzene, n-butylacrylate, and ethylene showed quantitative, 62%, and quantitative additions, respectively. Method 4 is the addition of nonhomopropagating monomers, that is, maleic anhydride.

Online H-1 NMR monitoring of the reaction has been used to investigate the living radical polymerizations. Polymerization of poly(ethylene glycol) methyl ether methacrylate macromonomer (MeO(PEG)MA; M-n = 480) was carried out in toluene mediated by a copper(I) bromide/N-(n-propyl)-2-pyridylmethanimine catalyst, using phenyl alpha -bromoisobutyrate (1) as initiator. The measured number-average molar mass, M-n, of the product increases linearly with monomer conversion in close agreement to the theoretical M-n, with low polydispersity products (PDI < 1.2) achieved in all cases, as expected for a living polymerization. The overall rate of polymerization was very fast (ca. 90% conversion after 1 h at 90 <degrees>C) when compared to polymerization of benzyl methacrylate (BzMA) under similar conditions, indicating high values for k(p)[R*], where R* = active propagating species. The origin of this dramatic rate enhancement was investigated by carrying out the polymerization of MeO(PEG)MA over a range of temperatures and by the polymerization of alkyl methacrylates with a MeO(PEG)-derived macroinitiator. Polymerization of BzMA was carried out in I,2-diethoxyethane as solvent, which showed an enhanced rate when compared to polymerization in nonpolar/noncoordinating solvents. The high value of k(p)[R*] is ascribed to complexation of the oxyethylene groups at the copper in a dynamic state with the pyridylmethanime ligand complexation, which results in a more active catalyst.},\n bibtype = {article},\n author = {Haddleton, David M and Perrier, Sébastien and Bon, Stefan A F},\n doi = {10.1021/ma001097c},\n journal = {Macromolecules},\n number = {22}\n}

The C(MBrMA)values using 2/DPw and Lambda were consistent, i.e., 1.28 and 1.20 for MMA and 11.44 and 10.92 for styrene, respectively. MBrMA was used as a chain-transfer agent in the emulsion polymerization of MMA to yield an a-bromo-functionalized macromonomeric latex ([M-n] = 9.6 x 10(3) g mol(-1); PDI = 1.80), which was subsequently copolymerized with styrene to yield the corresponding poly(styrene-graft-MMA) copolymer. MBrMA was used as an addition-fragmentation agent in the living radical polymerization of MMA mediated by copper(I) bromide/N-(n-octyl)-2-pyridylmethanimine In situ addition of a 5-fold equivalent of MBrMA and Cu(0) to this polymerization quenched the reaction and transformed the omega-bromide into the methacrylate-based macromonomer quantitatively.},\n bibtype = {article},\n author = {Bon, Stefan A.F. and Morsley, Stuart R. and Waterson, Carl and Haddleton, David M.},\n doi = {10.1021/ma991922t},\n journal = {Macromolecules},\n number = {16}\n}

It is shown that the isotropic correlation time (τc) of a nitroxide can be used as a measure of the diffusive rate coefficient of trapping (ketD). A general empirical relationship for the density of polystyrene as a function of molar mass and temperature is established to correct concentration data obtained from CRP experiments for volume contraction. It is demonstrated that the overall rates of polymerization of styrene in bulk do not show a dependence upon alkoxyamine concentration. Broadening of the molar mass distribution in a CRP experiment is ascribed to a low rate of alkoxyamine C-O bond homolysis and permanent chain-stopping reactions, e.g. bimolecular termination.},\n bibtype = {article},\n author = {Bon, Stefan A F and Bergman, Frank A C and Van Es, JJGS and Klumperman, Bert and German, Anton L},\n doi = {10.1021/bk-1998-0685.ch015},\n journal = {ACS Symposium Series}\n}

All of the catalysts were found to be effective atom-transfer polymerisation catalysts for the polymerisation of MMA in hydrocarbon solution.
