Abstract

The present invention relates to a flame retardant styrenic resin composition that comprises (A) about 5 to 95 parts by weight of a rubber modified styrene-containing resin; (B) about 95-5 parts by weight of polyphenylene ether; and (C) about 3-20 parts by weight of an oxaphospholane compound based on 100 parts by weight of the sum of (A) and (B). The resin composition of the present invention exhibits good flame resistance without the use of halogen flame retardant and does not emit harmful gases when burned.
