  The present invention provides an improved method for continuously producing a high-molecular-weight polycarbonate resin by carrying out a linking and highly-polymerizing reaction of an aromatic polycarbonate prepolymer with an aliphatic diol compound wherein the retention time of the reaction mixture in the linking and highly-polymerizing reactor is shortened to achieve excellent performance. The process comprises a process (A) for producing an aromatic polycarbonate prepolymer by polycondensation reaction of an aromatic dihydroxy compound with diester carbonate and a process (B) for conducting linking and highly-polymerizing reaction of the aromatic polycarbonate prepolymer with an aliphatic diol compound in the linking and highly-polymerizing reactor, wherein the aromatic polycarbonate prepolymer produced by the process (A) is fed continuously to the linking and highly-polymerizing reactor, while the aliphatic diol compound is fed continuously thereto under reduced pressure of 10 torr or less to carry out the reaction.

  A high molecular weight polycarbonate resin is continuously produced by subjecting an aromatic polycarbonate prepolymer and an aliphatic diol compound to a linking and highly polymerizing reaction. Even an aliphatic diol compound having a comparatively low boiling point can be allowed to efficiently contribute to the linking and highly polymerizing reaction. An aromatic polycarbonate prepolymer is produced by a polycondensation reaction between an aromatic dihydroxy compound and a diester carbonate, adding an aliphatic diol compound having an aliphatic group bonding to a terminal hydroxyl group to obtain a prepolymer mixture, and subjecting the resulting prepolymer mixture to a linking and highly polymerizing reaction under reduced pressure. The aliphatic diol compound is added at a pressure exceeding 200 torr, and the prepolymer mixture is subjected to a linking and highly polymerizing reaction before the terminal hydroxyl group concentration of the aromatic polycarbonate prepolymer in the prepolymer mixture reaches 2000 ppm.
