Claim Text:
1. A thermoplastic composition, comprising: (a) 50 to 95% by weight of at least one polyester-polycarbonate having a weight average molecular weight between 30,000 to 40,000 Daltons as measured by gel permeation chromatography polycarbonate standards and 5.0 mole % to 15.0 mole % sebacic acid and at least one polyester-carbonate having a weight average molecular weight between 15,000 to 25,000 Daltons as measured by gel permeation chromatography using polycarbonate standards and 5.0 mole % to 12.0 mole % sebacic acid; and (b) 5 to 50% by weight of at least one filler selected from glass, ceramic fiber, carbon fiber, a conductive filler, polytetrafluoroethylene, or a combination including at least one of the foregoing fillers; wherein the composition, as compared to a composition comprising a bisphenol A-based polycarbonate having at least one same filler and filler loading, has a melt volume rate as measured according to ASTM-D1238-10 that is at least 20% higher, an impact strength that is at least 20% higher, and a liquid particle count that is at least 20% lower.
