The aromatic polycarbonate prepolymer of step A is continuously fed to the linking reactor for increasing molecular weight and the aliphatic diol is continuously fed to the linking reactor for increasing molecular weight and reacted under conditions in which a degree of depressurization is 10 torr or less.
