ABSTRACT:
Hydroxymethylphosphorus compounds are insolubilized in and reacted with cellulosic textiles by combination with poly(ethyleneureas) and poly(N-methylolethyleneureas) to impart durable flame retardancy to the textile. The poly(ethyleneurea) or poly(N-methylolethyleneurea) may be employed as the sole coreactant for the hydroxymethyl phosphorus compound or as a supplement to urea, N-methylolureas, and the like.
