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 formation of radical centers. Analogous paramagnetic centers are detected directly in AA complexes with calcium nitrate. The ESR spectrum differs from that of -irradiated AA and is caused by nitroxyl radicals appearing in the course of the consecutive transformations in the system. The data obtained support the earlier suggested mechanism of NO₂-initiated polymerization of acrylamide complexes with metal nitrates.Translated fromIzvestiya Akademii Nauk.
