Under stirring and raising the mixture temperature up to 90° C., a solution of 107.7 g of acrylamide and 4.2 g of 2.2'-azobisisobutyrronitrile in 648 ml of ethanol was added thereto. The reaction mixture was kept at 90° C. for 20 hours and then poured into 2 liters of acetone; the precipitated product was grinded and washed upon decantation with one liter of acetone, filtered and dried. 108.6 g of a water soluble product were obtained, containing about 10% w/w of aminoallylidenmalononitrile moieties.
