| Abstract: | Acrylamide coordinated to Cr(III), Bi(III), Pb(II), and Ca(II) nitrates polymerizes spontaneously in concentrated aqueous solutions at  20°C with formation of glass-like polymers containing water. The process takes from several hours to several days, depending on reaction conditions and the nature of the metal nitrate. The product contains water-soluble and water-insoluble fractions. The insoluble fraction is polyacrylamide containing no metal compound. The possibility of spontaneous copolymerization of acrylamide complexes of metal nitrates with other water-soluble monomers was established.Institute of Energy Problems in Chemical Physics, Chernogolovka Branch, Russian Academy of Sciences, 142432 Chernogolovka.
