Notes:
Cellulose phosphonate was added to N,N-dimethylacrylamide (A) and 4-vinylpyridine (B) in the presence of sodium ethoxide to yield cellulose 2-(N,N-dimethyl)carbamoylethylphosphonate and cellulose 2-pyridinylethylphosphonate, respectively. The extent of the addition was 50% for (A) and 10% for (B), based on P - H bonds in cellulose phosphonate. The modification of cellulose with (A) resulted in an increase in the threshold temperature for weight loss, a decrease in the amount of residual products, and retardation of deammoniation of ammonium salts of the products. Modification of (B) resulted in a lower threshold temperature and amount of residue and an acceleration of the oxidation of cellulose chains. Cellulose phosphonate fabrics modified with (A) had powerful flame-retardant properties. It was deduced that the combination of phosphoryl and amide groups was an effectual flame retardant.
