Abstract
Solvent-resistant resin blends with a wide variety of desirable impact and tensile properties are prepared from a polyphenylene ether having a low proportion of unneutralized amino nitrogen, a mixture of a poly(alkylene dicarboxylate) and a polyarylate, an aromatic polycarbonate as a compatibilizing agent, and, optionally, at least one elastomeric polyphenylene ether-compatible impact modifier.
