Abstract: A thermoplastic molding material based on an impactresistant styrene polymer and on a polyphenylene ether, wherein the impact-resistant styrene polymer contains, as soft component, a graft copolymer of styrene to a copolymer of an alkyl acrylate, where alkyl is of 4 to 8 carbon atoms, and 0.5 to 10% by weight, based on total monomers, of a copolymerizable polyfunctional monomer, the soft component having a mean particle diameter of from 0.3 to 1.0 .mu.m. The novel molding materials possess improved flow and give moldings having improved aging resistance.

Abstract: of the Invention The invention relates to a process for the manufacture of a mixture of a polycarbonate and a styrenecontaining polymer whereby the polycarbonate present in solution is initially brought into contact with a precipitating agent. The solvent and the precipitating agent are subsequently separated from the precipitated solid material to prepare a polycarbonate having residual moisture of more than 1 and less than 50 percent by weight relative to the polycarbonate, and where the resultant product with a residual moisture is mixed with the styrene-containing polymer at temperatures above the softening range of the components removing volatile components The claimed mixtures are suitable for the manufacture of molded parts for cars, bottles and appliances.
