Abstract:
A polycarbonate resin composition comprising:a polycarbonate resin; and 100 to 500 ppm of a releasing agent, wherein said polycarbonate resin composition satisfies the following conditions: (1) a viscosity average molecular weight is from 10,000 to 17,000, (2) an iron content is 0.2 ppm or less; (3) when an intensity of a chemical shift &dgr; of from 7.0 to 7.5 ppm based on a phenyl ring in a spectrum measured with 1H-NMR is 1,000, a plurality of signal intensities at &dgr; of from 1.02 to 1.08 and from 6.69 to 6.73 are 0.01 or less; wherein said polycarbonate resin is obtained from a dihydric phenol which has been purified by contacting with an ion exchange resin after distillation of unreacted acetone, by-produced water and alkylmercaptan as an auxiliary catalyst.
