To a one-liter, 3-neck round bottom flask equipped with a heating mantle, nitrogen bubbler, stirrer, thermometer and reflux condenser were added 200 ml of deionized water and 75 g of sodium chloride. The solution was stirred under nitrogen for 30 minutes at room temperature and a solution of 30.0 g of 4-vinylpyridine, 3.0 g of N,N'-methylenebisacrylamide and 0.2 g of azobisisobutyronitrile in 90 ml of diisobutylketone was added. The temperature of the reaction solution was increased to between about 65° C. and about 70° C. with rapid stirring (200 rpm). After about 30 minutes some precipitate formed.
