Patent ID: 7019057

Claim:
A thermoplastic molding composition comprising A) 40 to 95 parts by weight of at least one member selected from the group consisting of aromatic polycarbonate and polyester carbonate, B) 0.1 to 25 parts by weight of polyalkyl (alkyl)acrylate, C) 0.1 to 25 parts by weight of a graft polymer the molecular structure of which is substantially free of units derived from any of styrene, butadiene and acrylonitrile, and including a graft base and a graft shell, said graft base containing a member selected from the group consisting of silicone rubber, acrylate rubber and silicone-acrylate composite rubber and said graft shell containing structural units derived from at least one (meth)acrylic acid (C 1 –C 8 -alkyl ester, D) 0.2 to 30 parts by weight of at least one compound conforming to wherein R 1 , R 2 , R 3 and R 4 independently of one another denote C 1 to C 8 -alkyl, or C 5 to C 6 -cycloalkyl, C 6 to C 20 -aryl or C 7 to C 12 -aralkyl, n independently of one another is 0 or 1 q is 0 to 30, and Y denotes C 1 to C 7 -alkylidene, C 5 to C 12 -cycloalkylene, C 5 to C 12 -cycloalkylidene, —O—or —S—, and E) 0 to 2 parts by weight of an anti-drip agent, and F) optionally at least one polymer additive selected from the group consisting of lubricants, mold release agents, nucleating agents, antistatics, stabilizers, light-stability agents, dyes, pigments, fillers, reinforcing agents, flameproofing agents different from component D, flameproofing synergists, polyphenylene oxides, polyesters, epoxy resins and novolak resins, wherein the total content of residual monomers of styrene, acrylonitrile and butadiene and structural units derived from such monomers bonded in polymeric constituents does not exceed 0.5% relative to the total weight of the composition.
