Abstract
The interaction between a number of inorganic salts and polyvinyl acetate (PVAc), a vinyl alcohol-vinyl acetate copolymer (VA-VAc) and polyvinyl alcohol (PVA) has been studied. It has been shown that, when perchlorates are introduced into solutions of PVAc or the VA-VAc copolymer in acetonitrile, the cation of the salt forms a donor-acceptor bond with the oxygen of hydroxyl and carbonyl groups of the polymers. When iodides are dissolved, in addition to these interactions, H bonds are formed in which the salt's anion and hydroxyl groups of the polymer participate. Possible types of transverse bonds between macromolecules in the gel forming systems studied are put forward; the role of the electrolyte in the formation of these bonds is explained.
