  The purpose of this invention is to produce a stabilized terminal-blocked polycarbonate resin with a limited number of the terminal hydroxy groups having excellent thermal stability, color stability and hydrolysis resistance by an industrially advantageous method using a terminal blocking agent. In the production of a polycarbonate by the melt-polycondensation of an aromatic dihydroxy compound with an aromatic carbonic acid diester in the presence of a polycondensation catalyst, a terminal blocking agent expressed by the following formula (1) [in the formula, R1 is chlorine atom, methoxycarbonyl group or ethoxycarbonyl group; R2 is an alkyl group having a carbon number of 1 to 30, an alkoxy group having a carbon number of 1 to 30, an aryl group having a carbon number of 6 to 30 or an aryloxy group having a carbon number of 6-30] is added after the melt-polycondensation to the system in an amount of 0.3 to 4 mol-equivalent based on the hydroxy terminal group amount of the polycarbonate at 200 to 350°C under a pressure of 1,013 hPa (760 mmHg) or below for 0.1 second or longer and, thereafter, a stabilizer is added and kneaded into the system at 200 to 350°C under a pressure of 1.333 × 105 hPa (105 mmHg) or below for 0.1 second or longer.

  本发明的目的是通过一种具有工业优势的方法，使用一种末端封端剂，生产一种稳定的末端封端聚碳酸酯树脂，该树脂具有数量有限的末端羟基，具有优异的热稳定性、颜色稳定性和耐水解性。 在缩聚催化剂存在下，通过芳香族二羟基化合物与芳香族碳酸二酯的熔融缩聚反应生产聚碳酸酯时，使用下式（1）表示的末端封端剂 [式中，R1 为氯原子、甲氧基羰基或乙氧基羰基；R2 为碳原子数为 1 至 30 的烷基、碳原子数为 1 至 30 的烷氧基、碳原子数为 6 至 30 的芳基或碳原子数为 6 至 30 的芳氧基]在熔融缩聚后加入到体系中，加入量为 0.在 200 至 350°C、1,013 hPa（760 mmHg）或以下的压力下，在 0.1 秒或更长的时间内，以聚碳酸酯的羟基末端基团量为基准，添加 3 至 4 摩尔当量的稳定剂，然后在 200 至 350°C、1.333 × 105 hPa（105 mmHg）或以下的压力下，在 0.1 秒或更长的时间内，将稳定剂加入并捏合到体系中。

  The relative intensity of fluorescent light of a melt-polycondensed aromatic polycarbonate produced by the transesterification process (melt polymerization process) of an aromatic dihydroxy compound and a carbonic acid diester in the presence of a catalyst comprising a basic nitrogen compound and/or a basic phosphorus compound in combination with an alkali metal compound is suppressed to 4.0×10-3 or below at a wavelength of 465 nm based on a standard substance in a fluorescent light spectrum obtained by the excitation wavelength of 320 nm. An aromatic polycarbonate having good color stability, especially good stability to the deterioration of the chip color during storage of the chip in air at room temperature can be produced by the present invention..
