- Abstract
Series of copolymers of <italic>N</italic>-methyl-<italic>N</italic>-vinylacetamide and <italic>N</italic>-methyl-<italic>N</italic>-vinylamine hydrochloride containing from 1.5 to 17% mol % of charged units were obtained by partial hydrolysis of poly(<italic>N</italic>-methyl-<italic>N</italic>-vinylacetamide). A complex of hydrodynamic investigations of their diluted solutions (viscous flow, velocity sedimentation, translational diffusion) was performed in 0.2 M NaCl in order to determine the molecular characteristics of copolymers. Viscosimetric investigations were performed in salt-free solution (ionic strength ~10-6 M) to study intrachain electrostatic interactions; the influence of charge linear density on the sizes of polyelectrolyte macromolecules was studied under these conditions. The examination of hydrodynamic volumes, equilibrium rigidity, and/or swelling coefficients of charged chains was performed.
