摘要： A method is provided for reducing the color generated during production of copolycarbonate that includes quinone-type residues. The method includes the steps of mixing the precursors of monomer residues, a carbonate source and a polymerization catalyst into a reaction mixture. The method further includes the steps of introducing an antioxidant such as a hydroxycarboxylic acid to the reaction mixture in an amount sufficient to reduce color formation and introducing the reaction mixture to a series of process units wherein the reaction mixture polymerizes. The resulting copolycarbonate has improved color as compared to a copolycarbonate formed in a process without the step of introducing an antioxidant to the melt polymerization process.

摘要： Polycarbonates containing low or undetectable levels of Fries rearrangement products and comprising repeat units derived from one or more of resorcinol, hydroquinone, methylhydroquinone, bisphenol A, and 4,4’-biphenol have been prepared by the melt reacti on of one or more of the aforementioned dihydroxy aromatic compounds with an ester-substituted diaryl carbonate such as bis-methyl salicyl carbonate. Low, or in many instances undetectable, levels of Fries rearrangement products are found in the product polycarbonates obtained as the combined result of a highly effective catalyst system which suppresses the Fries reaction and the use of lower melt polymerization temperatures relative to temperatures required for the analogous polymerization reactions using diphenyl carbonate.
