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: Provided are copolycarbonate compositions including a stabilizer package which comprise a phosphorous-containing acid, an ester of phosphorous-containing acid, and an organosulfonic stabilizer where the phosphorous-containing acid and the ester of a phosphorous-containing acid are present in a molar ratio of 1 to 2. The total stabilization package is for example, in the amount by weight of 4 to 32 ppm, 8 to 24 ppm, or 8 to 16 ppm and the organosulfonic stabilizer is, e.g., of 2 to 30 ppm, or 4 to 24 ppm, or 8 to 16 ppm.

Abstract: An article includes at least two contiguous layers containing a composition that includes a branched polycarbonate, optionally a linear carbonate-containing polymer, and 0 to less than 5 weight percent filler. The composition is characterized by an average mole percent branching of 0.06 to 2.4 mole percent, which is calculated as 100 times moles of branched carbonate units in the branched polycarbonate divided by the sum of moles of linear carbonate units in the branched polycarbonate and the optional linear carbonate-containing polymer. The composition is further characterized by a melt flow rate of 1 to 20 grams per 10 minutes, determined according to ASTM D1238-13 at 300° C. and 1.2 kilogram load. Also described is a method of additive manufacturing utilizing the composition.
