BLENDS OF AROMATIC POLYCARBONATE RESINS, POLYOLEFINS AND OLEFIN COPOLYMERS, AND ACRYLATE INTERPOLYMER RESINS

摘要

Thermoplastic molding compositions are described which comprise a miscible admixture of (a) an aromatic polycarbonate resin, (b) an olefinic polymer or copolymer and a minor amount of (c) a third component which is an acrylic polymer. The presence of the acrylic polymer permits the incorporation of amounts of component (b) in excess of 10 parts by weight per 100 parts by weight of (a) and (b) together to improve the stress cracking resistance without normally attendant loss in ductility.
