<P>PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition having improved chemical resistance and solvent resistance while maintaining the transparency, impact resistance, heat resistance, thermal stability and the like inherent in the polycarbonate resin. <P>SOLUTION: The polycarbonate resin composition comprises 100 pts.wt.polycarbonate resin (A), 0.01 to 20 pts.wt.specific alkyl ketene dimer (B) and 0.006 to 0.12 pts.wt.compound (C) to be a specific phosphorus based antioxidant. The polycarbonate resin composition has remarkably improved chemical resistance and solvent resistance and has improved hydrolysis resistance while maintaining excellent transparency, impact resistance, heat resistance, thermal stability and the like originating from a polycarbonate resin. Even when a molded product obtained from this resin composition adheres to hand cream, detergent and the like of various chemicals and a solvent, the occurrence of defects such as crack can be suppressed and even when exposed to an environment of high temperature and high humidity, an appearance defect such as cloudiness can be suppressed. Thereby this resin composition is industrially useful. <P>COPYRIGHT: (C)2013,JPO&INPIT |
