Abstract
For the first time, the interaction of polyvinyl alcohol and a copolymer of sodium salts of styrenesulfonic and maleic acids in aqueous solutions has been studied using the techniques of static and dynamic light scattering and capillary viscometry. It has been shown that hydrogen-bonded complexes are formed between them, with compaction of polyvinyl alcohol coils occurring in dilute solutions and additional structuring of the solution in semidilute solutions. The activation parameters (enthalpy and entropy) of viscous flow have been assessed, confirming the formation of the complexes. The concentration regimes of solutions of polyvinyl alcohol, the copolymer, and the complexes have been studied. It has been shown that the semidilute entanglement-free regime disappears in solutions of the complexes.
期刊介绍：
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
