A process for producing polycarbonate comprising contacting a dihydroxy capped carbonate and a diaryl carbonate in a reaction zone in the presence of a polymerization catalyst under polymerization conditions to produce polycarbonate. The dihydroxy capped carbonate is a carbonate with a dihydroxy compound on each end, and it is formed by the reaction of a dihydroxy compound with a dialkyl carbonate. The dihydroxy compound is a dihydroxy aromatic compound.
一种生产聚碳酸酯的工艺,包括在聚合催化剂存在的条件下,将二羟基封端碳酸酯和二芳基碳酸酯在反应区中接触,以生产聚碳酸酯。二羟基封端碳酸盐是一种两端各有一个二羟基化合物的碳酸盐,它是由二羟基化合物与二烷基碳酸盐反应生成的。二羟基化合物是一种二羟基芳香族化合物。
