Abstract:
1. A fiber or filament formed from ingredients comprising (a) at least one polybrominated anionic styrenic polymer, wherein the polybrominated anionic styrenic polymer has a bromine content of at least about 50 wt %, and a GPC weight average molecular weight of at least about 600,000; and (b) at least one fiber-forming thermoplastic polymer, wherein when the fiber-forming thermoplastic polymer is a polyester, the polybrominated anionic styrenic polymer is present in a flame resistant or a flame retardant amount, when the fiber-forming thermoplastic polymer is a polyamide, the polybrominated anionic styrenic polymer is at least about 2 wt % of the fiber or filament, and when the fiber-forming thermoplastic polymer is a polyolefin, at least one synergist is present and the polybrominated anionic styrenic polymer is no more than about 15 wt % of the fiber or filament.
