Abstract: 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).

Abstract: A thermoplastic composition includes: (a) from about 5 wt % to about 75 wt % of a polycarbonate component; (b) from about 10 wt % to about 60 wt % of a low refractive index polyester that is miscible with polycarbonate; (c) from about 10 wt % to about 30% of an inherently dissipative polymer (IDP) having a refractive index at room temperature of at least 1.50; and (d) from about 5 wt % to about 75 wt % of a copolymer comprising polycarbonate and isophthalate terephthalate resorcinol (ITR).

Abstract: Disclosed herein are thermoplastic compositions comprising: from about 0.01 wt. % to about 90 wt. % of a polyalkylene terephthalate, wherein the polyalkylene terephthalate component comprises at least a first and a second polyalkylene terephthalate polymer, wherein the first polyalkylene terephthalate has a molecular weight of from about 80,000 g/mol to about 300,000 g/mol as measured by gel permeation chromatography with polystyrene standards; from about greater than 0 wt. % to about 50 wt. % of a glass fiber; and from about 0.01 wt. % to about 45 wt. % of a high heat polymer, wherein the combined weight percent value of all components does not exceed 100 wt. %, and all weight percent values are based on the total weight of the composition.
