ABSTRACT:
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 formulawherein each Rfis independently a C1-12hydrocarbon, halogen, or halogen-substituted C1-12hydrocarbon, and u is 0 to 4; and from 10 to 90 mole percent of different carbonate units of the formulawherein at least 60% of the R1groups are C6-30aromatic groups, and from 1 to 99 weight percent of a polyester comprising units of the formulawherein T is a residue derived from a C5-C7cycloaliphatic or C7-C12aromatic dicarboxylic acid or a chemical equivalent thereof, and D is a residue derived from a C6-C12aromatic or C2-C12aliphatic 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.
