    摘要： A reactor system for producing polycarbonate includes a surface area in contact with a reaction mixture. The reaction mixture comprises a melt transesterification catalyst, a dihydroxy compound, a diaryl carbonate, and an phenolic byproduct. The surface area in contact with the reaction mixture contains one or more welds joining reactor system parts. All welds in contact with the reaction mixture join reactor system parts made from the same type of metal. If a filler metal is contained in the weld, the filler metal is made from the same type of metal as the metal parts joined by the weld.

    摘要： A method of making a polycarbonate is described. The method comprises melt reacting an ester-substituted diaryl carbonate and a multifunctional compound of the formula: in the presence of catalyst to form an oligomer comprising less than 2,000 ppm of an ester-linked terminal group, and melt polymerizing the oligomer to form a polycarbonate. Use of specific reaction conditions produces a polycarbonate having an Mw of greater than or equal to 25,000 g/mol as determined by gel-permeation chromatography relative to polystyrene standards. Polycarbonates comprising units derived from the multifunctional compound, including homopolycarbonates, aliphatic copolycarbonates further comprising units derived from an aromatic dihydroxy compound, and aliphatic polycarbonate-polyesters, are also disclosed, as are a thermoplastic composition and an article including the disclosed polycarbonates.
