Abstract

Water-soluble random copolymer of N-vinylformamide with sodium 4-styrenesulfonate is synthesized by free radical copolymerization. Copolymer fractions are studied by the methods of molecular hydrodynamics: viscometry, translational diffusion, and sedimentation velocity in dilute aqueous solutions. Molecular characteristics and scaling relations are obtained. Considerable differences in the conformational behavior of molecules of the copolymer and N-vinylformamide and sodium 4-styrenesulfonate homopolymers are discussed.

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.
