Abstract
A flame retardant thermoplastic resin composition comprises 100 parts by weight of a rubber-modified aromatic vinyl copolymer resin (A) and about 10 to about 30 parts by weight of a brominated diphenyl ethane mixture (B) including about 55 to about 85% by weight of hexabromodiphenyl ethane. The rubber modified aromatic vinyl copolymer resin (A) according to the present invention is a polymer resin wherein grafted rubbery polymers are dispersed in the form of particles in a matrix of vinyl copolymer. The rubber-modified aromatic vinyl copolymer resin (A) includes grafted rubbery polymers in an amount of about 10 to about 100% by weight and the matrix of vinyl copolymer in an amount of about 0 to about 90% by weight. The brominated diphenyl ethane mixture (B) may have about 1 to about 25% by weight of diphenyl ethane having an odd number of bromine substituents.
