  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..

  通过芳香族二羟基化合物和碳酸二酯在由碱性氮化合物和/或碱性磷化合物与碱金属化合物组合而成的催化剂存在下的酯化过程（熔融聚合过程）制得的熔融聚合芳香族聚碳酸酯，其荧光的相对强度在波长465 nm处被抑制到4.0×10-3或以下，该波长是基于由320 nm激发波长获得的荧光光谱中的标准物质。 通过本发明可以生产出一种具有良好颜色稳定性的芳香族聚碳酸酯，特别是在室温空气中储存芯片时对芯片颜色劣化具有良好的稳定性。

  A method for producing a high-quality thermoplastic branched polycarbonate which is used in blow-molding, extrusion or vacuum molding from a linear aromatic polycarbonate efficiently. The thermoplastic branched polycarbonate is produced by melt-mixing and reacting a substantially linear aromatic polycarbonate with an acid anhydride having at least two cyclic acid anhydride groups in a molecule in the presence of a basic catalyst.
