The conjugated effects of both reactive compatibilization and dynamic vulcanization on the phase inversion behavior of poly(butylene terephthalate) (PBT)/epoxide-containing rubber blends have been studied in detail. Pure ethylene-methyl acrylate random copolymer (E-MA) and ethylene-methyl acrylate-glycidyl methacrylate random terpolymer (E-MA-GMA) were used as non reactive or reactive rubber phase,...
The possibility to generate particle-in-particle morphology by controlling blending sequence has been investigated for reactive processing of poly(butylene terephthalate) (PBT) with ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) random terpolymer. Composite droplet morphology consisting of a PBT matrix, a E-MA-GMA dispersed phase and PBT sub-inclusions is spontaneously formed upon melt...
The influence of the functional groups concentrations on the reactive compatibilization of polybutylene terephthalate (PBT)/epoxide-containing rubber blends has been investigated by using various PBT and ethene-(methyl acrylate)-(glycidyl methacrylate) terpolymer (E-MA-GMA) grades. The reactivity of the rubber phase was modified using different strategies, including the use of commercial terpolymer...
Blends of polybutyleneterephthalate (PBT) with ethene–ethyl acrylate copolymer (E–EA) and ethene–methyl acrylate–glycidyl methacrylate terpolymer (E–MA–GMA) were investigated. E–MA–GMA terpolymers containing various concentrations of epoxide functions were synthesized in a preliminary step by melt modification of commercial E–MA–GMA with benzoic acid molecules. The blends were analyzed by several...
A 0.3 mm thick amorphous poly(ether ether ketone) (PEEK) film was exposed to acetone until equilibrium in the weight uptake was recorded, and was then dried in a vacuum oven at 70°C. The resulting structure was compared to the initial structure by means of differential scanning calorimetry (d.s.c.), wide-angle X-ray scattering (WAXS), small-angle X-ray scattering (SAXS), and infra-red (i.r.) spectroscopy...
