Abstract
The present invention provides a polycarbonate resin composition and molded articles made therefrom that have excellent flame retardancy and moldability. [Solution] A flame-retardant resin composition comprising 100 parts by weight of a polycarbonate resin composition containing (A) carbonate structural units derived from a divalent phenol compound, (B) siloxane structural units, and (C) structural units derived from 9,9-bis(4-hydroxy-3-alkylphenyl)fluorene, wherein the amount of Si element derived from (B) siloxane structural units is in the range of 0.3 to 30.0% by weight of the total structural units (100% by weight), and the content of structural units derived from (C) 9,9-bis(4-hydroxy-3-alkylphenyl)fluorene is in the range of 1.0 to 40% by weight, and (D) 1 to 20 parts by weight of a flame retardant of aluminum phosphate salt.
