FLAME-RETARDANT RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant resin composition which does not contain atoms as a halogen or phosphorus and is excellent in flame retardancy and molding flowability. SOLUTION: This flame-retardant resin composition contains 100 pts.wt. polycarbonate resin (A), 0.1-20 pts.wt. silicone compound (B) represented by mean composition formula (1): R<1> m R<2> n SiO(4-m-n)/2 (wherein R<1> is a 1-4C monovalent aliphatic hydrocarbon group; R<2> is a 6-24C monovalent aromatic hydrocarbon group provided R<1> and R<2> may each be in two or more kinds; and m and n satisfy the relations represented by 1.1<=m+n<=1.7 and 0.4<=n/m<=2.5), and 0.5-50 pts.wt. block copolymer (C) containing methacrylic polymer blocks and acrylic polymer blocks.
