The electroinitiated polymerization has been described here. The polymerization mixture consisted of monomer dissolved in an aqueous solution of ZnCl2, and was subjected to electrolysis in a divided cell. The rates of polymerization increased linearly with increase in applied current level and monomer concentration. Polymers of high molecular weights (≍105) were obtained from intrinsic viscosity measurements that increased with monomer concentration. The cyclic voltammogram of acrylamide in H2O -ZnCl2 solution suggests that the monomer gets directly reduced at cathode and the polymerization mechanism is anoinic.
