Flammhemmende organische Harzzusammensetzung

A flame retardant organic resin composition comprising (A) 100 parts by weight of an aromatic ring-containing organic resin and (B) 0.01-50 parts by weight of a branched organopolysiloxane described by average molecular formula (R 3SiO1/2)a(R SiO3/2)b(SiO4/2)c(R O1/2)d(HO1/2)e, where each R is independently selected from alkyl groups comprising 1 to 12 carbon atoms and alkenyl groups comprising 2 to 12 carbon atoms; each R is independently selected from alkyl groups comprising 1 to 12 carbon atoms, alkenyl groups comprising 2 to 12 carbon atoms, and aryl groups comprising 6 to 12 carbon atoms, where the aryl groups of R are at least 30 mol% based on total monovalent hydrocarbon in R and R , R represents an alkyl group, subscripts a and b are positive numbers, and subscripts c, d, and e are 0 or positive numbers.
