Abstract:
1. A thermoplastic molding composition comprising A) 60 to 99 percent by weight (pbw) aromatic poly(ester) carbonate having a weight-average molecular weight of at least 25,000, B) 1 to 40 pbw (co)polyester having an intrinsic viscosity from 0.94 deciliter/gram to 2.5 deciliter/gram, wherein the weight of A) and B) totals 100 parts (100 parts resin), C) 1 to 20 parts per 100 parts resin (phr) graft (co)polymer having a core-shell morphology, comprising a grafted shell that contains polymerized alkyl(meth)acrylate and a composite rubber core that contains interpenetrated and inseparable polyorganosiloxane and poly(meth)alkyl acrylate where the weight ratio of polyorganosiloxane/poly(meth)alkylacrylate/grafted shell is 70-90/5-15/5-15, D) 2 to 20 phr phosphorus-containing compound, E) 0.1 to 2 phr fluorinated polyolefin and F) 0.1 to 15 phr zinc borate having average particle diameter of 5 to 9 microns.
