AMIDE-UREA COPOLYMERS AND PROCESS FOR THE PREPARATION THEREOF

摘要

AMIDE-UREA COPOLYMERS AND PROCESS FOR THE PREPARATION THEREOF Copolymers comprising amide units and urea units are prepared by melt phase interchange of diaryl esters of dicarboxylic acids with diamines and diesters of carbonic acid with diamines. The products are tough resins, useful per se as molding compounds, or in blends with other thermoplastic polymers
