Abstract of  WO 2009079499  (A1)

A flame retardant polymer fiber, a process for making such a fiber, and a material containing such fibers are provided. The flame retardant polymer fiber is a high tenacity fiber formed of a poly(trimethylene terephthalate) co-polymer containing a trimethylene terephthalate monomer and a phosphorous containing flame retardant monomer. The flame retardant PTT co-polymer fiber is produced by a process in which the trimethylene terephthalate monomer or its precursors and the phosphorous containing flame retardant monomer or its precursors are combined to form the PTT co-polymer in one or more pre-polymerization and polymerization steps, and the PTT co-polymer is spun into a fiber. Materials including such flame retardant PTT co-polymer fibers, e.g. Carpets and textiles, are also provided.
