The diethyidiallylammonium bromide monomer was prepared in two steps. 60.5 Grams (0.5 mol) of allyl bromide were slowly added to 160 grams (2.20 mol) of diethylamine in 100 milliliters of acetone. After about 15 minutes, the solution became cloudy and white crystals of the byproduct, allyl ammonium hydrogen bromide, were formed. The solution containing allyldiethyl amine was filtered, and distilled at 112° C. under nitrogen to purify the material. The allyldiethyl amine was redissolved in 200 milliliters of acetone, and more allyl bromide added slowly. Crystals of the product, diallydiethylammonium bromide, precipitated out immediately. The product was recovered by filtration and washed with several quantities of acetone, and dried under vacuum.
