PROCESS FOR PRODUCING POLYCARBONATE

摘要

A method for manufacturing polycarbonate comprises: measuring a molar ratio of a carbonic acid diester to a dihydroxy compound in a reactor system using an online analyzer; controlling a supply of at least one of the dihydroxy compound and the carbonic acid diester to the reactor system so that the measured molar ratio is maintained within a selected range; and reacting the dihydroxy compound with the carbonic acid diester to produce the polycarbonate.
