摘要： A method for producing a transparent article comprises the steps of melt transesterifying a monomer mixture in the presence of a transesterification catalyst to produce a hydroquinone polycarbonate copolymer product comprising greater than 45 mole percent of structural units derived from the hydroquinone. The monomer mixture comprises a hydroquinone, at least one aromatic dihydroxy compound other than the hydroquinone, and a carbonic acid diester. The hydroquinone polycarbonate copolymer product is then heated to a highest processing temperature of 5° C. to 20° C. above a maximum melting melt temperature for the hydroquinone copolymer product for a sufficient period of time to render the hydroquinone polycarbonate copolymer product transparent upon cooling to ambient temperature; and cooling the hydroquinone polycarbonate copolymer product to produce the transparent article. The method can also be used for producing transparent hydroquinone polycarbonate copolymers, which can be used for producing the transparent articles.

摘要： Crystallinity of amorphous precursor polycarbonates is enhanced by contact with at least on diaryl carbonate such as diphenyl carbonate, followed by pelletization and heating to a temperature above the melting point of the diaryl carbonate and below the glass transition temperature of the amorphous precursor polycarbonate. The crystallinity enhancement operation may be conducted in the presence of dihydroxyorganic monomers and may be followed by a solid state polymerization operation.
