Provided are copolycarbonate compositions including a stabilizer package which comprise a phosphorus-containing acid, an ester of phosphorus-containing acid, and an organosulfonic stabilizer where thephosphorus-containing acid and the ester of a phosphorus-containing acid are present in a molar ratio of 1 to 2. The total stabilization package is for example, in the amount by weight of 4 to 32 ppm, 8 to 24 ppm, or 8 to 16 ppm and the organosulfonic stabilizer is, e.g., of 2 to 30 ppm, or 4 to 24 ppm, or 8 to 16 ppm. 提供了包含稳定剂组的共聚碳酸酯组合物，该稳定剂组包含含磷的酸、含磷的酸的酯和有机磺酸稳定剂，其中含磷的酸和含磷的酸的酯以1至2的摩尔比存在。总稳定组为例如按重量计4至32ppm，8至24ppm或者8至16ppm的量并且有机磺酸稳定剂为例如2至30ppm，或者4至24ppm，或者8至16ppm。
