US Patent:
55168558, May 14, 1996
Filed:
Jul 27, 1995
Appl. No.:
8/508324
Inventors:
Donald C. Clagett - Pittsfield MA
Daniel W. Fox - Pittsfield MA

Sheldon J. Shafer - Pittsfield MA
Assignee:
General Electric Company - Pittsfield MA
International Classification:
C08L 7700
US Classification:
525425
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.
