Abstract: Provided are copolycarbonate compositions including a stabilizer package which comprise a phosphorous-containing acid, an ester of phosphorous-containing acid, and an organosulfonic stabilizer where the phosphorous-containing acid and the ester of a phosphorous-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.
