Abstract: A thermoplastic composition includes: 40 to 75 wt % of a poly(carbonate-siloxane-arylate); 5 to 45 wt % of a poly(carbonate-siloxane) present in an amount effective to provide 0.75 to 7 wt % of siloxane units; 10 to 40 wt % of a polycarbonate homopolymer; 5 to 15 wt % of an organophosphorus compound in an amount effective to provide 0.1 to 1 wt % of phosphorus; and optionally, 0.1 to 10 wt % of an additive composition. The thermoplastic composition has a melt volume flow rate of greater than 6 cm3/10 min. An article molded from the thermoplastic composition has a 2-minute integrated heat release rate of less than or equal to 65 kW-min/m2 and a peak heat release rate of less than 65 kW/m2 and a notched Izod impact resistance of greater than 30 kJ/m2 or greater than 700 J/m2.

Abstract: A polycarbonate composition comprises: 30 to 95 wt % of one or more bisphenol A polycarbonate homopolymers; and 5 to 70 wt % of a poly(carbonate-siloxane) copolymer with a siloxane content of 10 wt. % to 25 wt. % based on the total weight of the poly(carbonate-siloxane), in an amount effective to provide a total siloxane content of 0.5 wt. % to 17.5 wt. % based on the total weight of the composition; the poly(carbonate-siloxane) copolymer comprising bisphenol carbonate units and siloxane units of the formulas or a combination comprising at least one of the foregoing, wherein E has an average value of 10 to 100, preferably 20 to 60, more preferably 30 to 50; wherein in the poly(carbonate-siloxane) copolymer less than 0.5 mol % of the siloxane units are directly coupled to another siloxane units.
