Abstract
A thermoplastic composition is provided which exhibits the combined properties of high gloss, reduced viscosity, desirable levels of dart impact strength and reduced levels of opacity. The compositions contain respective amounts of a bulk vinyl aromatic-vinyl cyanide-rubber graft copolymer, an emulsion vinyl aromatic-vinyl cyanide-rubber graft copolymer, a high molecular weight vinyl aromatic-vinyl cyanide rigid copolymer, and a low molecular weight vinyl aromatic-vinyl cyanide rigid copolymer. The emulsion graft copolymer utilizes as the rubber a vinyl aromatic-diene rubber. The thermoplastic compositions are useful for making molded articles exhibiting high gloss and desired levels of dart impact strength and opacity.
