Abstract: A thermoplastic composition comprising a highly branched polycarbonate comprising 1.5-5.0 mole % branching, wherein the highly branched polycarbonate has a weight average molecular weight of 25,000-45,000 grams per mole; a branched polycarbonate comprising 0.1-1.0 mole % branching, wherein the branched polycarbonate has a weight average molecular weight of 25,000-45,000 grams per mole; a first poly(carbonate siloxane) having 30-70 wt % siloxane, a second poly(carbonate siloxane) having 5-15 wt % siloxane, and wherein the total siloxane content provided to the thermoplastic composition by the first and second poly(carbonate-siloxanes) is less than 4.17 wt %; and wherein the ratio of the siloxane content provided to the thermoplastic composition by the first poly(carbonate siloxane) to the siloxane content provided to the thermoplastic composition by the second poly(carbonate siloxane) is less than 6.7 to 1, a flame retardant comprising a phosphorous-nitrogen bond; optionally, an auxiliary polycarbonate.

Abstract: Thermoplastic compositions include: (a) from about 30 wt % to about 95 wt % poly(methyl methacrylate) (PMMA); and (b) from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt %. Methods for making a molded article, include: (a) combining from about 30 wt % to about 95 wt % PMMA and from about 5 wt % to about 70 wt % of a poly(carbonate-siloxane) copolymer having a siloxane content of from about 25 wt % to about 45 wt % to form a blend; (b) melt processing and pelletizing the blend; and (c) injection molding the article from the melt processed and pelletized blend.
