    摘要： A fiber or filament which is formed from ingredients comprising (a) at least one fiber-forming thermoplastic polymer and (b) at least one polybrominated anionic styrenic polymer is provided. The polybrominated anionic styrenic polymer has a bromine content of at least about 50 wt %, and a GPC weight average molecular weight in the range of about 5000 to about 40,000, or a GPC weight average molecular weight of at least about 600,000. When the fiber-forming thermoplastic polymer is a polyester, the polybrominated anionic styrenic polymer is present in a flame resistant or 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. 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.

    摘要： N,N′-piperazinebis(neopentylglycol)phosphoramidate is used in combination with at least one co-additive which is (i) melamine, (ii) one or more melamine compounds or derivatives, or (iii) both of (i) and (ii) to provide effective flame retardancy in thermoplastic polymers. With polymers that tend to release trace amounts of acid under thermal processing conditions, a hydrotalcite is preferably included in the composition. In acid-sensitive polymers such as polyesters, the N,N′-piperazinebis(neopentylglycol)phosphoramidate should be free or essentially free of acid species as determinable by use of nmr, mass spec, and/or HPLC.
