ABSTRACT:
Tris(4-substitutedureidomethyl)phosphine oxides were prepared by the reaction of tris(hydroxymethyl)phosphine with substituted ureas. The phosphine oxides were used to impart flame retardancy to cellulosic materials. They were effective as flame retardants either alone or in combination with hydroxymethylphosphorus compounds or hydroxymethylnitrogen compounds.
