“…As a reactive compatibilization method, ester–ester and ester–amide exchange reactions have been studied for many years. The reactions for various polymer blends, such as PBS/Polyamide, EVA/PLA, PET/PC, PC/PMMA, etc., were studied, and it was found that some random or graft copolymers were generated by the exchange reactions. The reaction products, which acted as compatibilizer, could effectively improve the compatibility of the blends.…”
