Np. Piven et al., MODEL INVESTIGATION OF THE POLYMERIZATION OF ACRYLAMIDE COMPLEXES WITH METAL NITRATES BY ESR, Russian chemical bulletin, 43(3), 1994, pp. 494-496
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
.
