Abstract
Some features of the electrocopolymerization of acrylic acid and acrylamide in aqueous ammonium persulfate have been studied. UV spectroscopic and polarographic data attest to the intermolecular interaction of acrylic acid with acrylamide with the formation of 3∶1, 3∶2, and 1∶1 complexes; the former complex is the strongest. Electrochemical initiation of polymerization of monomers whose ϕ1/2 differ by ∼0.3 V can result in a copoiymer. The composition of the cathode polymeric coating has been determined by IR-spectroscopy and elemental analysis data. The molar ratios of acrylic acid to acrylamide in this coating and in the complex of the monomers are identical. The role of these complexes as elementary units in copolymerization is noted.
