A solution of 104 g of acrylamide, 800 ml of ethanol and 3.2 g of AZBN was then introduced therein. The obtained solution was left to reflux for 1 hour under stirring. A solution of 88 g of acrylamide, 400 ml of ethanol and 2.4 g of AZBN was introduced therein and the solution was left to reflux for 1 hour. A solution of 72 g of acrylamide, 400 ml of ethanol and 1.6 g of AZBN was added thereto and the obtained solution was left to reflux for 1 hour. A solution of 56 g of acrylamide, 400 ml of ethanol and 1.6 g of AZBN was finally added thereto and the obtained solution was left to reflux for 2 hours. The so-obtained mixture was cooled, filtered, washed with ethanol and then with ethyl ether and dried under vacuum at 50° C., thus obtaining 478 g of a water soluble product containing about 9% w/w of aminoallylidenmalononitrile moieties.
