A composition comprises a blend of 50 to 90 wt. % of a polycarbonate copolymer, 10 to 50 wt. % of a polyester wherein the weight percent of the polycarbonate copolymer and the polyester are each based on the total weight of the polycarbonate copolymer and the polyester. A molded sample of the composition having a thickness of 2.5 mm has a luminous transmittance of greater than 80% and a haze of less than 20% when measured in accordance with ASTM D 1003.

A composition comprises a blend of 20 to 90 wt. % of a polycarbonate, 10 to 80 wt. % of a polyester wherein the weight percent of the polycarbonate and the polyester are each based on the total weight of the polycarbonate and the polyester. A sample of the composition having a thickness of 2.5 mm has a luminous transmittance of greater than or equal to 80% and a haze of less than 20% when measured in accordance with ASTM D 1003.

A composition comprising a blend of: from 1 to 99 weight percent of a polycarbonate comprising from 10 to 90 mole percent of one or more arylate carbonate units of the formula wherein each Ris independently a Chydrocarbon, halogen, or halogen-substituted Chydrocarbon, and u is 0 to 4; and from 10 to 90 mole percent of different carbonate units of the formula wherein at least 60% of the Rgroups are Caromatic groups, and from 1 to 99 weight percent of a polyester comprising units of the formula wherein T is a residue derived from a C-Ccycloaliphatic or C-Caromatic dicarboxylic acid or a chemical equivalent thereof, and D is a residue derived from a C-Caromatic or C-Caliphatic diol or a chemical equivalent thereof, provided that at least 50 mole percent of D is derived from 1,4-cyclohexanedimethanol or a chemical equivalent thereof; and wherein the weight percent of the polycarbonate and the polyester are each based on the total weight of the polycarbonate and the polyester.
