Procedure

To a solution of 27.75 gm (0.25 mol) of N-vinylpyrrolidone and 169.5 gm (0.75 mol) of vinyl laurate in 460 gm of methanol were added 6 gm of azobisisobutyronitrile as catalyst. The resulting reaction mixture was agitated for 6 hours at 60° C, during which time the copolymer precipitated. After completion of the reaction, the methanol was distilled off and the polymer was washed a few times with fresh methanol. The yield was 176.5 gm (90% of theory) of N-vinylpyrrolidone/vinyl laurate copolymer (1:3 molar ratio).
