PURPOSE: The subject polycarbonate resin composition obtained by adding epoxy resin and aliphatic polyol to polycarbonate is provided, which has both excellent water resistance and flow properties as compared to conventional methods using only epoxy resin. CONSTITUTION: In polycarbonate thermoplastic resin, the resin comprises 100 parts by weight of polycarbonate, 0.02 to 0.3 parts by weight of aliphatic polyol of formula 1 having a number average molecular weight of more than 1,500 g/mol and 0.05 to 1.0 parts by weight of bisphenol type epoxy resin. wherein the polycarbonate resin has a melt flow index of 2 to 15 g/10min, which is measured by an ASTM D-1238 method and a density of 1.200 to 1.215 g/cm3, which is measured by an ASTM D-792 method and is obtained by polymerization of bisphenol A and phosgene. In formula, m, n are each an integer of from 0 to 150. |
