Аннотация:The complexation and photoreduction of silver cations by poly(acrylic acid) subjected to a partial decarboxylation under photolysis in the presence of oxygen were studied. It was shown that as the degree of decarboxylation grows, the constant of complex dissociation increases, the characteristic composition of the complex changes, and the cooperativity of binding is lost to an appreciable extent. The photoreduction of silver cations in the presence of the partially decarboxylated polyacid allows one to obtain stable particles of the rodlike type, and the length of these particles may achieve 500 nm.
