Blends of an aromatic polycarbonate, such as a polycarbonate of bisphenol-A, with a monovinylidene aromatic/carboxylic acid random copolymer, such as styrene/acrylic acid copolymer, exhibit improved impact strength and heat resistance. Such blends are particularly useful in the manufacture of molded parts which must be exposed to high temperature during manufacture and use. An example of a particularly desirable blend is a blend of a homopolycarbonate of bisphenol-A with styrene/acrylic acid copolymer and an acrylate resin containing grafted and nongrafted butadiene rubber and methyl methacrylate/ethyl acrylate random copolymer.
