AROMATIC POLYCARBONATE, PROCESS FOR PRODUCING THE SAME, AND COMPOSITION CONTAINING THE SAME

摘要

A polycarbonate having excellent color, a low content of foreign substances, a low content of an OH terminal group, little quality variation and excellent moldability and a production method therefor. The ester exchange of an oligocarbonate having a viscosity average molecular weight of 4,000 or more and a terminal hydroxyl group content of 15 to 45 mol% based on the total of all the terminal groups is further carried out while an ester exchange reaction accompanied by the elimination of an aromatic monohydroxy compound and an ester exchange reaction accompanied by the elimination of a diaryl carbonate compound are caused to take place in a ratio of 1:0.1 to 1:1.
