    Abstract: Flame-resistant acrylonitrile polymer textiles contains 4-25% phosphorus/nitrogen cpd of formula PN (OR) (OR') n PN Cl (OR") m (where n and m are O-10 and (n + m) is 3-10, and R,R' and R" are low-molecular monovalent organic residues. Phosphorus/nitrogen cpds are partly oily, partly crystalline substances, easily dispersible in aq. media; they need not be isolated after preparation but can be used in solution as produced. Cpds. are best applied to solutions of acrylonitrile polymers in aq. salt systems, such as zinc chloride solutions. Cpds are produced in known manner by reacting phosphorous dichloronitrides with hydroxyl cpds. in presence of bases.
