Abstract

Provided is a flame-retardant polycarbonate resin composition comprising (A) 100 parts by weight of a polycarbonate resin, (B) from 0.2 to 10 parts by weight of a core/shell type, grafted rubbery elastomer, (C) from 0.02 to 5 parts by weight of an organic alkali metal salt and/or an organic alkaline earth metal salt, and (D) from 0.02 to 3 parts by weight of a polyfluoro-olefin resin. Not containing a halogen compound for flame retardation, it has good flame retardancy, and its moldability, impact resistance, thermal stability, wet heat resistance and recyclability are all good.
