Abstract

The present invention relates to non-aging, impact-modified polycarbonate compositions and molding compositions comprising: A) from 60 to 86 parts by weight (based on the sum of components A+B+C) of aromatic polycarbonate and/or aromatic polyester carbonate, B) from 4 to 12 parts by weight (based on the sum of components A+B+C) of graft polymer comprising: B.1 from 10 to 50 wt. % (based on the graft polymer B) of a shell of at least one vinyl monomer, and B.2 from 90 to 50 wt. % (based on the graft polymer B) of a graft base of silicone-acrylate composite rubber, C) from 10 to 30 parts by weight (based on the sum of components A+B+C) of a polymer or copolymer based on vinyl monomer, and D) from 0 to 20 parts by weight of polymer additives.
