Plasticized, impact modified polycarbonates

Abstract

Novel thermoplastic molding compositions are disclosed which comprise (a) a bisphenol-A polycarbonate; (b) an alcohol terminated polyester of neopentyl glycol (2,2-dimethyl-1,3-propane-diol) and adipic acid; in admixture with (c) a minor amount of at least one component selected from the group comprising polyolefins, olefin based copolymers and olefin based terpolymers, such as, ethylene-propylene copolymers, ethylene-butadiene copolymers, propylene-butadiene copolymers, ethylene-propylene-butadiene terpolymers, ethylene-acrylic acid copolymers, propylene-acrylic acid copolymers, ethylene-ethyl acrylate copolymers, ethylene-vinyl acetate copolymers and ethylene-propylene-acrylic acid terpolymers; or (d) an amount of at least one component selected from the group comprising methyl methacrylate-butadiene-styrene copolymers, methyl methacrylate-acrylonitrile-butadiene-styrene copolymers and acrylonitrile-butadiene-styrene copolymers.
