发明名称 Aromatic polycarbonate
摘要 An aromatic polycarbonate of the present invention is produced by reacting an aromatic dihydroxy compound with a compound capable of introducing a carbonate bond, and has a viscosity-average molecular weight of 12,000 to 40,000 and a content of a cyclic oligomer represented by the formula (1) of not more than 1,000 ppm,in which the percentage of the content of said cyclic oligomer represented by the formula (1) based on the total contents of the cyclic oligomer represented by the formula (1), an oligomer represented by the formula (2) and an oligomer represented by the formula (3) satisfies the following relational formula [I]:wherein (1), (2) and (3) are contents of the oligomers represented by the above formulae (1), (2) and (3), respectively; and Mv is a viscosity-average molecular weight of said aromatic polycarbonate.
