PURPOSE:A thermoplastic resin composition that is obtained by adding a specific amount of a specific phosphorus compound and an alkylated phenol antioxidant to polycarbonate, thus showing improved discoloration and deterioration is physical properties, when melted with heat and having high impact strength and clarity. CONSTITUTION:A polycarbonate resin from 1,1-bis(4-hydroxyphenyl)ethane is combined with (A) 1-500X10<-5>wt%, calculated based on phosphorus atom, of a phosphorus compound selected from the group consisting of phosphorus acid and phosphite esters and (B) 1-500X10<-3>wt% of an alkylated phenol antioxidant such as 2,6-di-t-butyl-4-nonylphenol. |
