Modification of the ω-bromo end group of poly(methacrylate)s prepared by copper(I)-mediated living radical polymerization. Bon, S., A., F., Steward, A., G., & Haddleton, D., M. Journal of Polymer Science, Part A: Polymer Chemistry, 38(15):2678-2686, John Wiley & Sons, Inc., 2000. ![Modification of the ω-bromo end group of poly(methacrylate)s prepared by copper(I)-mediated living radical polymerization [link]](https://bibbase.org/img/filetypes/link.svg "link")
Website doi abstract bibtex Four different approaches to introduce a specific functional group at the terminus of poly(methacrylate)s (PMMAs) prepared via copper(I)bromide/pyridinali- mine-mediated atom transfer polymerization, under polymerization conditions, are reported. 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. This reaction proceeds quantitatively.
