  An article includes at least two contiguous layers containing a composition that includes a branched polycarbonate, optionally a linear carbonate-containing polymer, and 0 to less than 5 weight percent filler. The composition is characterized by an average mole percent branching of 0.06 to 2.4 mole percent, which is calculated as 100 times moles of branched carbonate units in the branched polycarbonate divided by the sum of moles of linear carbonate units in the branched polycarbonate and the optional linear carbonate-containing polymer. The composition is further characterized by a melt flow rate of 1 to 20 grams per 10 minutes, determined according to ASTM D1238-13 at 300 °C and 1.2 kilogram load. Also described is a method of additive manufacturing utilizing the composition.

  In a continuous flow reactor one or more bisphenols is converted by the action of phosgene and aqueous base into a mixture of mono- and bisphenol chloroformates which are then treated with a catalyst, additional aqueous caustic and a monophenol to afford endcapped polycarbonates. At relatively high levels of added monophenol endcapped polycarbonate oligomers are obtained. The method is especially suited for the continuous preparation of endcapped oligomers of tetrabromobisphenol A polycarbonate. The method is characterized by efficient use of phosgene, and conversion of chloroformate groups to carbonate linkages aided by trialkylamine catalysts bearing at least one methyl group on nitrogen, such as N,N-dimethylbutylamine (DMBA).

  在一个连续流动的反应器中，一种或多种双酚在光气和水碱的作用下转化成单酚和双酚氯甲酸酯混合物，然后用催化剂、额外的水性苛性碱和单酚进行处理，得到端帽聚碳酸酯。当添加的单酚含量较高时，可得到端帽聚碳酸酯低聚物。该方法特别适用于连续制备四溴双酚 A 聚碳酸酯的内封端低聚物。该方法的特点是高效使用光气，并在氮上含有至少一个甲基的三烷基胺催化剂（如 N,N-二甲基丁胺（DMBA））的帮助下，将氯甲酸酯基团转化为碳酸酯链节。
