Fractions of the copolymer of N-methyl-N-vinylacetamide and N-methyl-N-vinylamine hydrochloride containing 15.7 ± 0.5% of charged units are obtained by radical polymerization, fractionation, and hydrolysis. Viscous flow, velocity sedimentation, and translational diffusion of their dilute solutions are studied in 0.2 M NaCl. Viscosimetric studies are also carried out in a wide range of ionic forces: from the minimum (~10^–6 mol/L) to the maximum (6 mol/L). The hydrodynamic volumes and equilibrium rigidity of the copolymer under study are compared with the data obtained earlier for an uncharged homopolymer and a copolymer with a higher linear charge density (~44% of charged units) in solutions with different ionic strength. The correspondence of the values obtained to the theories of Odijk, Skolnik, and Fixman (OSF) as well as Dobrynin is discussed.

通过自由基聚合，分馏和水解，获得含有15.7±0.5％的带电单元的N-甲基-N-乙烯基乙酰胺和N-甲基-N-乙烯基胺盐酸盐的共聚物的级分。在0.2 M NaCl中研究了其稀溶液的粘性流动，速度沉降和平移扩散。粘度分析还可以在多种离子力下进行：从最小（〜10 ^–6mol / L）至最大值（6 mol / L）。将研究中的共聚物的流体力学体积和平衡刚度与较早获得的数据进行比较，该数据是在不同离子强度的溶液中不带电均聚物和具有较高线性电荷密度（〜44％的带电单元）的共聚物。讨论了获得的值与Odijk，Skolnik和Fixman（OSF）以及Dobrynin的理论的对应关系。
