Résumé / Abstract Molecular characteristics (Mw, A2, 1/2, Kuhn segment A, [η]) of poly(2-acrylamide-2-methyl-propanesulfonic acid) and its copolymers with acrylamide were examined in aqueous saline solutions using light scattering and viscometry. Viscometric measurements were conducted at various ionic strengths I and pH of the medium. The content of SO3- groups in polyanion varied from 21 to 95 wt%. At I=1 mol l-1, molecular characteristics of the polymer were similar to those of uncharged flexible-chain polymers Revue / Journal Title Polymer science ISSN 0965-545X Source / Source 1992, vol. 34, no12, pp. 1028-1032 (23 ref.)
