Notes:
The Co-60 γ-radiation-induced polymerization of ethenesulfonamide is extremely rapid. The monomer is converted to polymer at the rate of 75%/hr. at 4200 r/min. as compared to rates of 1-17%/hr. for other monomers under similar conditions. The polymer shows the viscosity characteristics of a polyelectrolyte (intrinsic viscosity of 0.5 at 0.125% in dimethylformamide) and is estimated to have molecular weight of M̄n 12,000 and M̄w 50,000 from a preliminary evaluation of viscosity, osmotic, and light scattering data, Gi values of 170-40 are indicated for the polymerization on the basis of estimated molecular weights of 12,000-50,000.
