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 reaction 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.

摘要： A method for preparing a molded article includes the steps of (a) obtaining a polycarbonate resin and (b) molding the polycarbonate resin. The polycarbonate resin is made by a transesterification reaction using an activated diaryl carbonate such that the polycarbonate is susceptible to the formation of internal ester linkages (IEL). The method occurs with the proviso that the polycarbonate resin, the molding conditions or both are selected to control the amount of IEL formed during the molding process to a level of less than 0.4 mol %.

摘要： Polycarbonates incorporating terminal carbonate groups derived from ester-substituted activated carbonates in a transesterification process have unfavorable properties with respect to color, hydrolytic stability and thermal stability, particularly when the polycarbonate containing such end groups is molded. The number of activated carbonate end groups formed during the melt transesterification formation of polycarbonate can be reduced by reacting a dihydroxy compound with an activated diaryl carbonate in the presence of an esterification catalyst to produce a polycarbonate, in the presence of a monohydroxy chainstopper such as para-cumyl phenol in an amount that results in 35 to 65 mol % of the end groups being derived from the monohydroxy chainstopper. Suitably, the reactants are provided such that the molar ratio of activated diaryl carbonate to the total of dihydroxy compound plus ½ the chainstopping reagent that is less than 1.

摘要： Polycarbonates incorporating terminal carbonate groups derived from ester-substituted activated carbonates, for example terminal methyl salicyl carbonate (TMSC) derived from the use of BMSC as the activated carbonate in a transesterification process, have unfavorable properties with respect to color, hydrolytic stability and thermal stability, particularly when the polycarbonate containing such end groups is molded. The number of activated carbonate end groups formed during the melt transesterification formation of polycarbonate can be reduced, however, without sacrificing the benefits of using an activated diaryl carbonate, and without requiring a separate reaction or additional additives by reacting a dihydroxy compound with an activated diaryl carbonate in the presence of an esterification catalyst to produce a polycarbonate, wherein the molar ratio of activated diaryl carbonate to dihydroxy compound is less than 1 when expressed to at least three decimal places, for example 0.996 or less.

摘要： Stable, homogeneous melt solutions are prepared at temperatures of 200° C. or less from solid mixtures comprising at least one diaryl carbonate, at least one high melting dihydroxy aromatic compound (mp>200° C.), a transesterification catalyst, and optionally a lower melting dihydroxy aromatic compound. Thus, a stable, homogeneous melt solution is obtained from a solid mixture comprising 4,4′-biphenol (mp 282-284° C.) at a temperature of about 200° C. using either diphenyl carbonate or bis(methyl salicyl) carbonate as the diaryl carbonate component. It is shown that formation of the stable, homogeneous melt solutions requires the presence of the transesterification catalyst when substantial amounts of the high melting dihydroxy aromatic compound are present in the initial solid mixture. Solid mixtures comprising a variety of high melting bisphenols; 4,4′-biphenol; 3,3,3,3′-tetramethylspirobiindanbisphenol, and 4,4′-sulfonyidiphenol are converted to stable, homogeneous melt solutions at 200° C., a temperature substantially below the melting points of the high melting bisphenols in their pure states.

摘要： This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl)carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising ester-substituted phenoxy terminal groups.
