摘要： A catalyzed interfacial phosgenation process with controlled feed ratios and controlled reaction pH levels allows for the formation of high heat polycarbonate random copolymers having high loadings of bis (4-hydroxyphenyl)-2-phenylisoindolin-1-one (“PPPBP”) or a structurally related comonomer. The process produces a polycarbonate copolymer having improved hydrolytic stability.

摘要： A method of preparing a poly(ester-carbonate) includes contacting an aqueous solution including a dicarboxylic acid with a first solution including phosgene and a first organic solvent in a tubular reactor to provide a first reaction mixture. A dihydroxy aromatic compound, the corresponding dialkali metal salt of the dihydroxy aromatic compound, or a combination comprising at least one of the foregoing, water, and a second organic solvent are combined to provide a second reaction mixture. The method further includes introducing the first reaction mixture, the second reaction mixture, and a second solution comprising phosgene to a tank reactor, wherein the tank reactor has a first pH of 7 to 10. The pH is optionally raised to 9 to 11 to provide a third reaction mixture including the poly(ester-carbonate). Poly(ester-carbonate)s prepared according to the method described herein are also disclosed.
