The redox copolymerization of acrylonitrile with acrylamide in N, N-dimethylformamide (DMF) containing K2S2O8 and AgNO3 was carried out. The resulting copolymers were soluble in this solution. A white floppy mass was obtained, when poltmerizing solution was poured in cold methanol. The copolymers were formed taking different feed ratios of monomers and concentrations of the initiators at 60°C. As the concentration of acrylamide increased in the feed ratio, copolymer yields consierably increased. The copolymerization was completely inhibited by 2, 2-diphenyl-1-picrylhydrazyl suggesting a free radical reaction.
