Abstract:
A flame retardant resin composition comprising(A) 100 parts by weight of a synthetic resin containing phenyl rings, and (B) 0.1 to 10 parts by weight of an organopolysiloxane containing phenyl radicals attached to silicon atoms and containing in its molecule 10 to 75 mol % of siloxane units represented by R1R2R3SiOÂ½, 0 to 80 mol % of siloxane units represented by R4R5SiO{fraction (2/2)}, 11 to 80 mol % of siloxane units represented by R6SiO{fraction (3/2)}, and 0 to 15 mol % of siloxane units represented by SiO{fraction (4/2)}, wherein R1, R2, R3, R4, R5 and R6 are independently selected from substituted or unsubstituted monovalent hydrocarbon radicals of 1 to 6 carbon atoms, the contents of alkoxy radicals and hydroxyl radicals available as Siâ€”OH radicals in a molecule each being less than 2% by weight, said organopolysiloxane having a weight average molecular weight of up to 2,000.
