Summary:A thermoplastic composition is disclosed, comprising: a polymer component comprising a polyestercarbonate copolymer comprising ester units and carbonate units; a polycarbonate copolymer comprising branched carbonate units. and carbonate units; and 0.01 to 10 wt.%, based on the total weight of the polymer component, of a polymeric compound comprising at least two epoxy groups, wherein the polymeric compound has a weight average molecular weight of 1,500 to 18,000; wherein a test article having a thickness of 3.2 mm and molded from the thermoplastic composition retains more ductility after aging at 134 DEG C and 100% humidity for 48 hours than an article having a thickness of 3.2 mm and molded from the same thermoplastic composition without the polymeric compound comprising at least two epoxy groups, each measured in accordance with ASTM D3763-02.
