Hydrodynamic, molecular, and conformational characteristics of macromolecules of a random copolymer of N-Methyl-N-vinylacetamide and N-Methyl-N-vinylamine Hydrochloride

The development and optimization of processes involving polymeric molecules require determination and monitoring of key molecular characteristics of the polymer. Samples of poly- N -methyl- N -vinylacetamide were synthesized and fractionated. Partial hydrolysis of the homopolymer fractions was perfo...

Summary:The development and optimization of processes involving polymeric molecules require determination and monitoring of key molecular characteristics of the polymer. Samples of poly- N -methyl- N -vinylacetamide were synthesized and fractionated. Partial hydrolysis of the homopolymer fractions was performed, and fractions of a random copolymer of N -methyl- N -vinylacetamide and N -methyl- N -vinylamine hydrochloride were obtained. The molecular weights and conformational parameters of the homo- and copolymers in 0.2 M aqueous NaCl were determined by methods of molecular hydrodynamics.
