Abstract
Copolymers comprising amide units and ester units are prepared by melt phase interchange of diaryl esters of dicarboxylic acids and diamines with dihydric alcohols and diesters of aromatic dicarboxylic acids. The products are tough resins, useful per se as molding compounds, and to compatibilize and toughen other thermoplastic polymers.
