发明名称 Method for producing polycarbonate
摘要 The present invention relates to a process for the production of an aromatic polycarbonate by a polycondensation reaction or a solid phase polymerization reaction under a flow of an inert gas, wherein an alcohol or a phenol, which is produced as a by-product, is separated from the inert gas using a scrubber. In accordance with the present invention, since the by-product can be separated efficiently, an aromatic polycarbonate can be produced under a flow of an inert gas by an efficient and simplified process.
