  • Tris(ureidomethyl)phosphine oxides
    Patent number: 4102923
    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.
    Type: Grant
    Filed: September 8, 1975
    Date of Patent: July 25, 1978
    Assignee: The United States of America as represented by the Secretary of Agriculture
    Inventors: Armand B. Pepperman, Jr., Donald J. Daigle, Sidney L. Vail
  • Water soluble adduct of hydroxymethyl phosphorous compound and ammonia or amine compound and method of preparation
    Patent number: 4071501
    Abstract: Soluble adduct polymers were allowed to react with phenol, alkyl substituted phenols or halogen substituted phenols which contain one or more hydrogens ortho or para to the phenolic hydroxyl group to (a) prepare flame resistant polymers and (b) prepare flame-, glow-, wrinkle- and shrink-resistant woven and knit textiles which contain 25% or more cellulosic fibers.
