Abstract
The present invention relates to a flame retardant thermoplastic resin composition that comprises (A) about 40 to 95 parts by weight of a rubber modified styrene-containing resin, (B) about 5 to 60 parts by weight of polyphenylene ether resin, (C) about 2 to 30 parts by weight of a styrene-containing copolymer resin having about 5 to 18 % by weight of acrylonitrile in the copolymer per 100 parts by weight of the sum of (A) and (B), (D) about 0.5 to 20 parts by weight of an oxaphospholane compound per 100 parts by weight of the sum of (A) and (B), and (E) about 0 to 30 parts by weight of a phosphoric acid ester compound per 100 parts by weight of the sum of (A) and (B).
