Abstract
Copolymerizable monoethylenic phosphites are produced by reacting an N-methylol allyl carbamate with a stoichiometric excess of a trialkyl phosphite. The monoethylenic phosphonate product can be copolymerized, especially with N-methylol acrylamide in water solution to provide water solutions of copolymers which cure at low temperature on cellulosic fabrics to provide fire retardancy and the phosphorus provided in this fashion resists removal by washing and dry cleaning.
