| abstract |
A di lower alkyl phosphite acrylamide or methacrylamide, preferably with formaldehyde and tetrakis (hydroxymethyl) phosphonium halide are reacted to form a compound of the formula WHERE R1 and R2 are lower alkyl R3 is hydrogen or methyl and R4 is hydrogen or methylol. The compounds are useful as fire retardants, particularly in textiles, paper and other forms of cellulosic fibers as well as synthetic fibers. |
