Abstract

Provided is a method for manufacturing a polycarbonate resin that is capable of keeping the quality thereof wherein the formation of foreign matters is prevented and therefore the obtained polycarbonate resin is hardly contaminated with foreign matters. The method for manufacturing a polycarbonate resin whereby the polycarbonate resin is continuously manufactured by employing a plurality of reaction devices characterized in that at least one of the reaction devices said reaction device being designed so that the viscosity average molecular weight of the polycarbonate resin at the outlet of the reaction device attains 10 000 or greater is provided with an agitation axis and a scraper.
