A reinforced polycarbonate composition includes 30-60 wt % of a homopolycarbonate; 5-30 wt % of a poly(carbonate-siloxane); 10-40 wt % of a high heat polycarbonate having a glass transition temperature of 170° C. or higher determined per ASTM D3418 with a 20° C./min heating rate; 1-10 wt % of a phosphorous-containing flame retardant present in amount effective to provide 0.1-1.5 wt % phosphorous; 0.01-0.5 wt % of an anti-drip agent; 5-30 wt % of a reinforcing fiber; and optionally, up to 10 wt % of an additive composition, wherein each amount is based on the total weight of the reinforced polycarbonate composition, which sums to 100 wt %. A molded sample of the polycarbonate composition has a heat deflection temperature greater than 115° C., preferably greater than 125° C., more preferably greater than 130° C., or a flame test rating of V1, preferably V0 as measured according to UL-94 at a thickness of 0.8 millimeter, or at a thickness of 0.6 mm, or at a thickness of 0.4 mm.

Reinforced polycarbonate compositions with improved heat resistance

Described herein are cold-sintered ceramic polymer composites and processes for making them from ceramic precursor materials and monomers and/or oligomers. The cold sintering process and wide variety of monomers permit the incorporation of diverse polymeric materials into the ceramic.
