Procedure

A reaction mixture was prepared by dissolving 22.2 gm (0.2 mol) of N-vinylpyrrolidone and 119.5 gm (0.5 mol) of lauryl acrylate in 330 gm of toluene and adding 2.8 gm of dibenzoyl peroxide as catalyst. The reaction mixture was agitated for 6 hours at 80° C. After the reaction had been completed, the solvent was distilled off and the polymer was washed a few times with methanol. 133 gm (95% of theory) of N-vinylpyrrolidone/lauryl acrylate copolymer (1:2.5) were obtained.
