Abstract
Aryl ester-grafter polyphenylene ethers are prepared by heating a polyphenylene ether with an olefinic aryl ester, usually an unsubstituted or substituted phenyl acrylate. The products react with lactams such as .epsilon.-caprolactam in the presence of lactam polymerization catalysts to produce phenylene ether-amide copolymers.
