Vs. Savostyanov et al., PREPARATION AND REACTIVITY OF METAL-CONTAINING MONOMERS .21. SPONTANEOUS POLYMERIZATION OF ACRYLAMIDE COORDINATED TO METAL NITRATES, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(9), 1992, pp. 1615-1620
Acrylamide coordinated to Cr(III), Bi(III), Pb(II), and Ca(II) nitrate
s polymerizes spontaneously in concentrated aqueous solutions at appro
ximately 20-degrees-C with formation of glass-like polymers containing
water. The process takes from several hours to several days, dependin
g on reaction conditions and the nature of the metal nitrate. The prod
uct contains water-soluble and water-insoluble fractions. The insolubl
e fraction is polyacrylamide containing no metal compound. The possibi
lity of spontaneous copolymerization of acrylamide complexes of metal
nitrates with other water-soluble monomers was established.
