Impact-modified polycarbonate compositions

A composition consisting essentially of

• A) from 40 to 99 parts by weight, in each case based on the sum of the parts by weight of components A+B+C+D, of an aromatic polycarbonate and/or aromatic polyester carbonate,
• B) from 0.5 to 20 parts by weight, in each case based on the sum of the parts by weight of components A+B+C+D, of a first graft polymer, wherein the graft base is a silicone-acrylate composite rubber of interpenetrating silicone rubber and polyalkyl (meth)acrylate rubber, wherein the amount of silicone rubber is from 65 to 95 wt. %, based on the graft base,
• C) from 0.5 to 20 parts by weight, based on the sum of the parts by weight of components A+B+C+D, of a second graft polymer comprising a copolymer that is not chemically bonded to rubber, and having a weight-average molecular weight of from 60,000 to 150,000 g/mol,
• D) from 3 to 16 parts by weight, based on the sum of the parts by weight of components A+B+C+D, of at least one polymer selected from the group consisting of rubber-free vinyl (co)polymer and polyalkylene terephthalate, and
• E) optionally from 0.5 to 25 parts by weight, in each case based on the sum of the parts by weight of components A+B+C+D, of at least one additive selected from the group consisting of lubricants, demoulding agents, nucleating agents, stabilisers, antistatics, acids, fillers, reinforcing materials, colourings and pigments.
