Abstract

Compatible compositions comprising polyarylene sulfide-polyphenylene ether copolymers are prepared by the reaction of a polyphenylene ether containing epoxy groups, typically an epoxytriazine-capped polyphenylene ether, with a polyarylene sulfide containing epoxide-reactive functional groups, preferably amine groups. It is sometimes advantageous to anneal said compositions or molded articles prepared therefrom.
