ABSTRACT:
Polymer blend compositions comprise a polyphenylene ether polymer, a styrene-acrylonitrile polymer and a copolymer compatiblizing agent in an amount sufficient to effect improved compatability between the polyphenylene ether polymer and the styrene-acrylonitrile polymer. The copolymer compatabilizing agent comprises a graft copolymer of A graft polymerized to B or a block copolymer of A block polymerized with B. A and B comprise polymers which are immiscible with one another, and one of A and B is miscible with the polyphenylene ether polymer while the other of A and B is miscible with the styrene-acrylonitrile polymer.
