    Abstract: The present invention relates to a polymer composition comprising a transparent polymer blend. The polymer blend comprises a first resin and a second resin. The first resin comprises polyarylate structural units of formula I, wherein R1 is independently at each occurrence a C1–C2 alkyl group, or a halogen atom, and p is 0 to 3. The second resin is selected from the group consisting of polycarbonates, polyarylates and copolyestercarbonates. The first resin and the second resin are further characterized by a difference in polyarylate structural unit content, said difference being less than about 40 mole percent.

    Abstract: Block copolyestercarbonates substantially free of anhydride linkages linking at least two mers of the polymer chain may be prepared by a method which comprises the steps of: (A) preparing a hydroxy-terminated polyester intermediate in a molten reaction mixture comprising at least one 1,3-dihydroxybenzene moiety and at least one aromatic dicarboxylic acid diarylester under transesterification conditions, said polyester intermediate having a degree of polymerization of at least 4; and (B) conducting a reaction of said polyester intermediate with a carbonate precursor in a two-phase system comprising an aqueous phase and a water-immiscible organic solvent. Articles comprising the copolyestercarbonates are another aspect of the invention.

    Abstract: Thermally stable block copolyestercarbonates comprising chain members derived from at least one dihydroxy-substituted aromatic hydrocarbon moiety and at least one aromatic dicarboxylic acid moiety, said polymer being substantially free of anhydride linkages linking at least two mers of the polyester chain segments, are prepared by a method comprising the steps of: (a) preparing a hydroxy-terminated polyester intermediate comprising structural units derived from at least one dihydroxy-substituted aromatic hydrocarbon moiety and at least one aromatic dicarboxylic acid moiety; and (b) conducting a reaction of the polyester intermediate with phosgene in a reaction mixture comprising water, a substantially water-immiscible organic solvent, and a base, wherein base and phosgene are added simultaneously to the reaction mixture at a substantially constant molar ratio of base to phosgene for a time period of at least about 60% of the total amount of phosgene added.
