ABSTRACT:
Solvent-resistant resin blends, capable of being molded into parts which vary in properties relatively little over a wide range of molding conditions, are prepared from a polyphenylene ether, a linear polyester such as a poly(alkylene dicarboxylate), a mixture of a bisphenol A homopolycarbonate and block copolymer of a polyphenylene ether and a bisphenol A polycarbonate. Said blends preferably also contain at least one elastomeric polyphenylene ether-compatible impact modifier.
