Abstract:
A thermoplastic composition comprising: a copolycarbonate comprising bisphenol A (BPA) carbonate units and 10-50 mol % of second carbonate units different from the BPA carbonate units; a poly(carbonate-arylate ester) copolymer comprising BPA carbonate units and 5-50 mol % of monoaryl arylate ester units; and optionally a BPA homopolycarbonate; wherein the thermoplastic composition has at least one of: a Vicat B120 softening temperature of 155° C. or greater; or a yellowness index of less than 10 on a plaque having a thickness of 3 mm and molded at a temperature of 360° C. for 5 minutes; or an increase in yellowness index of less than 5 after 600 hours of weathering per ISO 11341 on a molded plaque having a thickness of 1 mm.
