To the solution obtained were added 3.1 gm of dibenzoyl peroxide as a catalyst. The reaction mixture was maintained for 5 hours under stirring at a temperature of 80° C. After the reaction was completed, the solvent was distilled off and the reaction product washed several times with methanol. 147 gm (95% of theory) of N-hydroxymethyl acrylamide/dodecyl acrylate copolymer (1:6 molar ratio) were obtained.
