Abstrakt:	N-Methyl-N-vinylacetamide–N-methyl-N-vinylamine copolymer of 85 : 15 mol % composition was prepared by partial hydrolysis of poly-N-methyl-N-vinylacetamide. Alkylation of the copolymer with dodecyl iodide yielded a water-soluble comb-shaped copolymer of N-methyl-N-vinylacetamide with N-methyl-N-vinyl-N-dodecylamine iodide containing hydrophobic С12Н25 groups in the side chain. This copolymer was studied by methods of molecular hydrodynamics: viscometry, translational diffusion, and sedimentation velocity in dilute solutions. Hydrodynamic and molecular characteristics of the copolymers were determined, and Kuhn–Mark–Houwink–Sakurada canonical relationships were obtained. [ABSTRACT FROM AUTHOR]
