    • The present inventors have developed flame retardant thermoplastic resin compositions which 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.
    • 本发明人开发了阻燃热塑性树脂组合物,其包含100重量份的橡胶改性的芳族乙烯基共聚物树脂(A)和约10至约30重量份的溴化二苯乙烷混合物(B),其包含约55至 约85重量%的六溴二苯乙烷。 根据本发明的橡胶改性芳族乙烯基共聚物树脂(A)是其中接枝橡胶状聚合物以乙烯基共聚物基质中的颗粒形式分散的聚合物树脂。 橡胶改性的芳族乙烯基共聚物树脂(A)包括约10至约100重量%的接枝橡胶聚合物和约0至约90重量%的乙烯基共聚物基体。 溴化二苯乙烷混合物(B)可以具有约1至约25重量%的具有奇数个溴取代基的二苯基乙烷。
