Patent ID: 8445624

Claim:
A process for producing a polycarbonate, comprising subjecting one or more dihydroxy compounds comprising a dihydroxy compound having at least one linking group —CH 2 —O— in a molecule thereof to melt polycondensation with a carbonic acid diester in at least two serially arranged reactors to produce a polycarbonate, wherein, in the reactors, a difference between a temperature of a polymer and a temperature of a heating medium is regulated to 80° C. or smaller when the polycarbonate yielded has a reduced viscosity of 0.10 dL/g or lower, or to 60° C. or smaller when the polycarbonate yielded has a reduced viscosity exceeding 0.10 dL/g but not higher than 0.40 dL/g, or to 40° C. or smaller when the polycarbonate yielded has a reduced viscosity exceeding 0.40 dL/g.
