Acrylonitrile as monomer, azobisisobutyronitrile as initiator, hexamethylenetetramine as ligand, copper chloride dihydrate as catalyst and Vitamin C as reducing agent, polyacrylonitrile was synthesized in N,N-dimethylformamide under the light irradiation. The effects of the amount of monomer, initiator, catalyst, hexamethylenetetramine and Vitamin C on the photo-induced polymerization of acrylonitrile have been invetigated. On the basis of experiments, it is concluded that the best polymerization conditions were that the amount of monomer is 0.2 mol and the usage of azobisisobutyronitrile, copper chloride dihydrate, hexamethylenetetramine and vitamin C was 1%, 0.75%, 1%, 4 % of the mole of monomer, respectively. The best reaction time is 11 h.
