    摘要： 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.

    摘要： 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.

    摘要： In one aspect, the present invention provides a method for recovering bitumen from an oil sand, the method comprising: (a) contacting a bitumen-containing oil sand with a first solvent mixture of cyclohexane and ethanol to provide an extraction mixture comprising a sand phase and an organic phase; (b) separating the sand phase from the organic phase comprising bitumen, ethanol and cyclohexane; (c) separating an azeotropic mixture comprising cyclohexane and ethanol from the organic phase; and (d) recovering bitumen from the organic phase. The first solvent mixture comprises from about 95 to about 65 percent cyclohexane and from about 5 to about 35 percent ethanol.
