  Provided is an improved method for continuously producing a high molecular weight polycarbonate resin by subjecting an aromatic polycarbonate prepolymer and an aliphatic diol compound to a linking and highly polymerizing reaction, wherein even an aliphatic diol compound having a comparatively low boiling point can be allowed to efficiently contribute to the linking and highly polymerizing reaction, and a high molecular weight polycarbonate resin of superior quality can be produced both economically and advantageously. Provided is a method which comprises producing an aromatic polycarbonate prepolymer by a polycondensation reaction between an aromatic dihydroxy compound and a diester carbonate, adding thereto an aliphatic diol compound having an aliphatic group that bonds to a terminal hydroxyl group to obtain a prepolymer mixture, and subjecting the resulting prepolymer mixture to a linking and highly polymerizing reaction under a reduced pressure condition, wherein the aliphatic diol compound is added at a pressure exceeding 200 torr, and then, 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.

  本发明提供了一种通过使芳香族聚碳酸酯预聚物和脂肪族二元醇化合物进行连接和高度聚合反应来连续生产高分子量聚碳酸酯树脂的改进方法，其中即使是沸点相对较低的脂肪族二元醇化合物也可以有效地促进连接和高度聚合反应，从而既经济又有利地生产出高质量的高分子量聚碳酸酯树脂。 本发明提供了一种方法，该方法包括通过芳香族二羟基化合物和碳酸二酯之间的缩聚反应生产芳香族聚碳酸酯预聚物，在其中加入具有与末端羟基键合的脂肪族基团的脂肪族二元醇化合物以获得预聚物混合物、将得到的预聚物混合物在减压条件下进行连接和高度聚合反应，其中脂肪族二醇化合物在超过 200 托的压力下加入，然后，在预聚物混合物中芳香族聚碳酸酯预聚物的端羟基浓度达到 2000 ppm 之前，将预聚物混合物进行连接和高度聚合反应。

  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.
