摘要： Aliphatic tricarboxylic acids, as exemplified by 9-carboxy-1,18-octadecanedioic acid, may be prepared by the biotransformation of an olefinic monocarboxylic acid such as oleic acid to the corresponding olefinic dicarboxylic acid, preferably 1,18-octadec-9-enedioic acid, in the presence of a strain of yeast, such as a strain of Candida tropicalis, followed by the carboxylation of the olefinic dicarboxylic acid by reaction with carbon monoxide and water in the presence of a catalyst. The product tricarboxylic acids are useful as branching agents for polycarbonates.

摘要： The present invention discloses a vapor phase method of introducing a branching agent such as THPE into a solid polycarbonate while simultaneously crystallizing the solid polycarbonate. The partially crystalline polycarbonate containing a branching agent introduced in this manner is suitable for use in the preparation of branched polycarbonates by solid state polymerization. Branching in the polycarbonates so produced is demonstrated by rheometric measurements. Such branched polycarbonates are known to possess increased material melt strength, shear sensitivity, and complex viscosity ratio, and are particularly well-suited in blow molding applications.

摘要： The present invention discloses improved copolycarbonates and methods for their synthesis that involve the incorporation of aliphatic diol carbonates into copolycarbonate chains under solid state polymerization conditions. More particularly, the present invention utilizes diphenyl carbonate in the production of copolycarbonates that exhibit modified thermal properties(lower Tg) relative to analogous simple copolycarbonates. The solid sate polymerization technique possesses a distinct advantage over melt polymerization in that no specialized melt polymerization equipment is required.
