Evidence of Melt Reaction Between Poly(3-Hydroxybutyrate-co-3-Hydroxyhexanoate) and Epoxidized Natural Rubber as Investigated by DSC, Isothermal TGA and FTIR Analyses. Salim, Y. S., Saiter, J., Natarajan, V. D., Kumar, S., Neon, G. S., & Han, C. C. Macromolecular Symposia, 365(1):81–86, 2016. Paper doi abstract bibtex This work describes properties of a new polymeric system obtained after melt reaction between poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) [P(3HB-co-3HHx)] with 40% (in mass) of epoxidized natural rubber (ENR). Differential scanning calorimetry (DSC), thermogravimetry, infra-red spectroscopy and confocal optical microscopy analysis were performed on this system. Before melt reaction, we found that ENR particles with diameters of more than 2 µm were homogeneously distributed in P(3HB-co-3HHx) phase using confocal optical microscope. From infrared spectroscopy, reaction engaged during the thermal cycle for sample preparation, leads to a melt reaction associated with inhibition of crystallization of P(3HB-co-3HHx) in the blend. This is also observed in DSC analysis. Furthermore, a progressive mass loss of up to 10% was observed after five half-time of melt reaction by utilizing isothermal procedure in thermogravimetry.
