Abstract:
A flame retardant resin composition comprising(A) 100 parts by weight of a resin comprising 10 to 100% by weight of an aromatic polycarbonate resin and 90 to 0% by weight of a thermoplastic resin other than the aromatic polycarbonate resin, (B) 0.1 to 9.9 parts by weight of an organopolysiloxane containing silicon atom-bonded phenyl groups in a molecule and having the average compositional formula (1): R1mR2n(OR3)p(OH)qSiO(4-m-n-p-q)/2â€ƒâ€ƒ(1) â€ƒwherein R1 is a phenyl, R2 is hydrogen or a monovalent hydrocarbon group of 1 to 6 carbon atoms excluding phenyl, R3 is a monovalent hydrocarbon group of 1 to 4 carbon atoms, letters m, n, p and q are numbers satisfying 0.1&lE;m&lE;2.0, 0.2&lE;n&lE;2.5, 0&lE;p&lE;1.5, 0&lE;q&lE;0.35 and 0.9&lE;m+n+p+q&lE;2.8, and (C) 0.1 to 9.9 parts by weight of an organopolysiloxane containing silicon atom-bonded methyl group and Siâ€”H groups in a molecule and free of an aromatic hydrocarbon group, the amount of components (B) and (C) combined being 0.2 to 10 parts by weight, said organopolysiloxane (B) containing (1) phenyl, methyl, C1-4 alkoxy groups bonded to silicon atoms in a molecule, or (2) containing silicon atom-bonded phenyl and methyl groups and Siâ€”H groups in a molecule wherein a Siâ€”H content is from 0.1 to 1.2 mol/100 g.
