Abstract

Mixtures of polyphenylene ethers, lactams such as .epsilon.-caprolactam and lactam polymerization catalysts, preferably basic reagents, may be polymerized. There is preferably also present a lactam polymerization promoter, especially a functionalized polyphenylene ether. Polymerization produces resinous compositions including phenylene etheramide copolymers, especially block and/or graft copolymers. Said resinous compositions may be molded into articles having a number of advantageous properties.
