    摘要: Impact-modified polycarbonate compositions are disclosed that comprise a first graft polymer based on silicone-acrylate composite rubber as graft base, wherein the amount of silicone rubber is from 65 to 95 wt. % (based on the graft base), and a second graft polymer containing free copolymer, that is to say copolymer that is not chemically bonded to the rubber, and having a weight-average molecular weight of from 60,000 to 150,000 g/mol. The use of the polycarbonate compositions in the production of molded articles, and to the molded articles themselves are also disclosed. The compositions and molding compositions have an optimum combination of good elongation at tear, good hydrolytic stability and low melt viscosity.
