Abstract (en)
[origin: WO2014164096A1] The present invention provides 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 20 parts per 100 parts resin (phr) graft (co)polymer having a core-shell morphology, comprising a grafted shell that contains poliymerized 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, C) 2 to 20 phr phosphorus-containing compound, and D) 0.1 to 15 phr boron compound having average particle diameter of 2 to 10 microns.
