Polymer alloys based on poly(2,6-dimethyl-1,4-phenylene ether) and poly(styrene-co-acrylonitrile) using poly(styrene-b-(ethylene-co-butylene)-b-methyl methacrylate) triblock copolymers as compatibilizers

摘要: Poly(styrene-b-(ethylene-co-butylene)-b-methyl methacrylate) (P(S-b-EB-b-MMA) triblock copolymers containing various amounts of the elastomeric center block (6-38 wt% PEB) have been used to compatibilize polymer blends based on poly(2,6-dimethyl-1,4-phenylene ether) (PPE) and poly(styrene-co-acrylonitrile) (PSAN). From dynamic mechanical analysis TEM, detailed information about location is obtained, because intermixing PS with PPE PMMA PSAN changes glass transitions main components. In all studied blends, penetrates into
