PROCESS FOR PRODUCTION OF AROMATIC POLYCARBONATES

摘要

Aromatic polycarbonates excellent in physical properties and hue are produced via simplified steps as compared with those of the prior art. A process for the production of aromatic polycarbonates which comprises the following steps (1) to (3): the step of preparing a bisphenol A/phenol composition by reacting phenol with acetone in the presence of an acid catalyst to convert part of the phenol into bisphenol A, the step of feeding the bisphenol A/phenol composition in a fluid molten state to the production step of aromatic polycarbonate, and the step of reacting the bisphenol A with a starting carbonate to produce an aromatic polycarbonate.
