Patent ID: 8710127

Claim:
A composition comprising A) from 77 to 90 parts by weight (based on the sum of components A+B+C) of linear and/or branched aromatic polycarbonate and/or aromatic polyester carbonate, B) from 6 to 12 parts by weight (based on the sum of components A+B+C) of graft polymer having B.1 from 5 to 30 wt. % (in each case based on the graft polymer B) of a shell of at least one vinyl monomer and B.2 from 95 to 70 wt. % (in each case based on the graft polymer B) of one or more graft bases of silicone-acrylate composite rubber, C) from 4 to 10 parts by weight (based on the sum of components A+B+C) of phosphorus compounds according to formula (VIII) wherein R 1 , R 2 , R 3 and R 4 , independently of one another, represent optionally halo-substituted C 1 -C 8 -alkyl, in each case optionally halo- and/or alkyl-substituted C 5 -C 6 -cycloalkyl, C 6 -C 10 -aryl or C 7 -C 12 -aralkyl, the substituents n independently of one another represent 0 or 1, the substituents q independently of one another represent 0, 1, 2, 3 or 4, N represents from 0.1 to 10, R 5 and R 6 , independently of one another, represent C 1 -C 4 -alkyl, or halogen, and Y represents a single bond, C 1 -C 7 -alkylidene, C 1 -C 7 -alkylene, C 5 -C 12 -cyclo-alkylene, C 5 -C 12 -cycloalkylidene, —O—, —S—, —SO—, —SO 2 — or —CO—, D) from 0 to 3 parts by weight (based on the sum of components A+B+C) of at least one anti-dripping agent, and E) from 0 to 3 parts by weight (based on the sum of components A+B+C) of thermoplastic vinyl (co)polymer (E.1) and/or polyalkylene terephthalate (E.2); and F) from 0 to 20 parts by weight (based on the sum of components A+B+C) of at least one further additive, wherein the weight ratio of component B to the phosphorus content from component C is in a range of from 16 to 22 to 1, and wherein the composition is free of rubber-free polyalkyl (alkyl)acrylate wherein the composition has a fire behavior UL94V of V0 and a transition temperature tough/brittle notched impact test of no greater than −15° C.
