Reaction Steps

Next, to a 1-L 3-necked round-bottomed flask equipped with a mechanical stirrer and a reflux condenser was added 625 g of the 20.0 wt. % solution of styrene-co-1-vinylimidazole in DMF. Benzyl chloride (8.0 g) was added, and the solution was stirred and heated at 100° C. under a slight positive pressure of nitrogen for 18 hr. A portion of the solution (25 g) was removed for analysis. Then, 9.7 g of 2-chloroethanol was added, and the solution was reheated with stirring at 100° C. for an additional 18 hr. The reaction mixture was cooled and the polymer was precipitated into diethyl ether with rapid stirring. The flaky precipitate was washed well with diethyl ether and dried in a vacuum oven.
