A thermoplastic composition includes: (a) from about 5 wt% to about 90 wt% of an aliphatic polyester-polycarbonate copolymer; (b) from about 5 wt% to about 65 wt% of a polycarbonate component different from the aliphatic polyester-polycarbonate copolymer in element (a); and (c) from greater than 5 wt% to about 30 wt% of an inherently dissipative polymer (IDP). The composition has a heat distortion temperature of at least 90 °C at 1.8 MPa and 4.0 mm as determined in accordance with ISO 75 and a notched Izod impact strength at 23 °C of at least 25 kJ/m2 as tested in accordance with ISO 180 at a thickness of 4.0 mm. In further aspects the composition has improved surface gloss properties as compared to a comparative composition that does not include the aliphatic polyester-polycarbonate copolymer of element (a).
