Patent ID: 8779050

Claim:
A composition consisting of A) from 60 to 86 parts by weight, based on the sum of components A+B+C, of an aromatic polycarbonate and/or an aromatic polyester carbonate, B) from 4 to 12 parts by weight, based on the sum of components A+B+C, of a 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 a silicone-acrylate composite rubber, wherein the silicone-acrylate composite rubber comprises an interpenetrating network of silicone rubber and acrylate rubber, C) from 10 to 30 parts by weight, based on the sum of components A+B+C, of at least one rubber-free vinyl (co)polymer of C.1 from 50 to 99 parts by weight, based on component C, of a vinyl aromatic compound and/or a vinyl aromatic compound substituted on the ring and/or a (meth)acrylic acid (C1-C8)-alkyl ester, and C.2 from 1 to 50 parts by weight, based on component C, of a vinyl cyanide and/or a (meth)acrylic acid (C1-C8)-alkyl ester and/or an unsaturated carboxylic acid and/or an anhydride of an unsaturated carboxylic acid and an imide of an unsaturated carboxylic acid, and D) from 0 to 20 parts by weight, based on the sum of components A+B+C, of at least one polymer additive selected from the group consisting of flameproofing agents, flameproofing synergists, antidripping agents, lubricants and mould release agents, nucleating agents, stabilisers, antistatics, colourings and pigments wherein components B and C are present in a ratio of the parts by weight of B:C in a range from 1:1.3 to 1:3.5, and wherein the composition is free of inorganic filler.
