Реферат: MIXTURES INCLUDING POLYPHENYLENE ETHERS AND LACTAMS AND RESINOUS COMPOSITIONS PREPARED THEREFROM ABSTRACT OF THE DISCLOSURE Mixtures of polyphenylene ethers, lactams such as .epsilon.-caprolactam and lactam polymerization catalysts, prefer-ably basic reagents, may be polymerized. There is prefer-ably also present a lactam polymerization promoter, especi-ally a functionalized polyphenylene ether. Polymerization produces resinous compositions including phenylene ether-amide copolymers, especially block and/or graft copolymers. Said resinous compositions may be molded into articles hav-ing a number of advantageous properties.
Reactive elastomeric block co-oligomer and lactam- block copolymers derived therefrom
