Reinforced flame retardant polycarbonate compositions with improved melt volume rates

A reinforced polycarbonate composition comprising

• 50-95 wt % of a poly(aliphatic ester-carbonate);
• 5-40 wt % of a high heat copolycarbonate comprising high heat carbonate units derived from 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethyl-cyclohexane, N-phenyl phenolphthalein bisphenol, 4,4′-(1-phenylethylidene)bisphenol, 4,4′-(3,3-dimethyl-2,2-dihydro-1H-indene-1,1-diyl)diphenol, 1,1-bis(4-hydroxyphenyl)cyclododecane, 3,8-dihydroxy-5a, 10b-diphenyl-coumarano-2′,3′,2,3-coumarane, or a combination thereof;
• 0.1-0.8 wt % of a C1-16 alkyl sulfonate salt flame retardant;
• 0.1-0.8 wt % of an anti-drip agent;
• 5-35 wt % glass fibers;
• optionally 0.1-10 wt % of an additive composition,
• optionally 1-30 wt% of a polycarbonate different from the poly(aliphatic ester-carbonate), the high heat copolyca rbonate, and the poly(carbonate-siloxane), wherein the polycarbonate has a molecular weight of less than 24,000 grams per mole, as measured via gel permeation chromatography using polystyrene standards and calculated for polycarbonate;
• and
• wherein each amount is based on the total weight of the reinforced polycarbonate composition, which sums to 100 wt %.
