Radiation-Induced Addition of Flame Retardants to the Double Bond in Acrylamidomethyl Cellulose

Abstract

Cotton and rayon fabrics were condensed with N-methylol acrylamide to give products with various degrees of un saturation. Radiation-induced free-radical addition to the double bonds in these fabrics was accomplished with carbon tetrachloride, bromoform, chloroform, bromotetrachloromethane, polyethylene oxide, chloral and bromal hydrate, and sodium hypophosphite. Stannous and stannic chloride were also reacted by what seems to be a different mechanism. Bromination of these fabrics is also described. Significant flame retardancy was obtained without alteration of hand, because the reactions are limited to the inside of the cellulose fiber.
