Reaction Conditions

Reaction Steps

In a 10 liters flask, supplied with stirrer, reflux and internal thermometer, 230 g. of acrylamide and 120 g. of 3-diallylaminoallylidenemalononitrile (A) were dissolved in 4 liters of ethanol at 96%. The mixture temperature was increased to 78° C. under agitation. 8 g. of 2,2'-azobisisobutyrronitrile (AZBN) were introducted at this point. After 10 minutes, a yellowish product began separating. The reaction was continued under those conditions for 14 hours. The mixture was then cooled at room temperature; the separated product was filtered, washed with diethyl ether and vacuum dried at 50° C. The yield of the solid yellowish product was 320 g., with 8% aminoallylidenemalononitrile units in weight. The IR, spectrophotometric analysis and the TLC confirmed for the polymer a structure with allylidenemalononitrile groups. The solution at 6% in 70/30 water/ethanol diluted 1:2000 in water showed an optical density of 0.7 at 382 nm.
