Compatibilization of PBT PPE blends using low molecular weight epoxyPolymer Engineering Faculty Research
AbstractCompatibilization of blends of an immiscible polymeric system consisting of poly(butylene terephthalate) (PBT) and poly(phenylene ether) (PPE) by a set of low molecular weight epoxy, varying in chain flexibility and functionality, was studied in terms of morphology and mechanical properties. Evidences, such as reduction of epoxide peak in FT-IR spectra and viscosity and glass transition temperatures higher than PBT of melt-blended materials of PBT–epoxy indicated formation of PBT–epoxy copolymers, which in turn compatibilized and stabilized the morphology in PPE–PBT–epoxy blends. Significant improvements in tensile and impact strengths resulted.
