ABSTRACT:
Blends of aromatic polyestercarbonate copolymers with aromatic polycarbonate resins provide improved low temperature toughness while maintaining tensile strength essentially equivalent to the polycarbonate component. Particularly preferred components are polycarbonates of bisphenol A and a polyestercarbonate derived from bisphenol A, phosgene and terephthaloyl and isophthaloyl chlorides.
