MODEL INVESTIGATION OF THE POLYMERIZATION OF ACRYLAMIDE COMPLEXES WITH METAL NITRATES BY ESR

Modelling experiments have shown that the interaction between NO2 and acrylamide (AA) and the AA complex with calcium nitrate leads to the f ormation of radical centers. Analogous paramagnetic centers are detect ed directly in AA complexes with calcium nitrate. The ESR spectrum dif fers from that of gamma-irradiated AA and is caused by nitroxyl radica ls appearing in the course of the consecutive transformations in the s ystem. The data obtained support the earlier suggested mechanism of NO 2-initiated polymerization of acrylamide complexes with metal nitrates .
