  Disclosed herein is an aromatic polycarbonate resin containing benzophenone and benzoate ester derivatives which have a molecular weight less than 1,000, each in an amount of 100 ppm or less. Also disclosed is a process for preparing an aromatic polycarbonate resin from an aromatic dihydroxy compound and a carbonate diester in which the benzophenone derivative content is 100 ppm or less by transesterification, comprising preparing a polycarbonate prepolymer having a viscosity average molecular weight of 5,000 to 20,000 using an iminocarboxylic acid or salt thereof as a transesterification catalyst and polymerizing the prepolymer in an extruder. Phosphoric acid mono- or diesters, phosphorous acid diesters or phosphorous acid are optionally added as stabilizers during the preparation process. The aromatic polycarbonate is colorless and transparent and is suitable for extrusion molding.

  本发明公开了一种芳香族聚碳酸酯树脂，其中含有二苯甲酮和苯甲酸酯衍生物，这两种衍生物的分子量小于 1,000，含量均为 100 ppm 或更少。本发明还公开了一种通过酯交换反应从芳香族二羟基化合物和碳酸酯二酯制备芳香族聚碳酸酯树脂的工艺，其中二苯甲酮衍生物含量为 100 ppm 或更少，该工艺包括使用亚氨基甲酸酯或其盐作为酯交换反应催化剂制备粘度平均分子量为 5,000 至 20,000 的聚碳酸酯预聚物，并在挤压机中聚合该预聚物。在制备过程中，可选择添加磷酸单酯或磷酸二酯、磷酸二酯或磷酸作为稳定剂。 芳香族聚碳酸酯无色透明，适合挤出成型。
