Conformational parameters of poly(N-methyl-N-vinylacetamide) molecules through the hydrodynamic characteristics studies.

Water-soluble PMVA was synthesized by radical polymerization methods. A number of polymer samples were fractionated in the chloroform-diethyl ether system. Fractions were studied by molecular hydrodynamics methods (sedimentation velocity, translational isothermal diffusion and viscosity) in H(2)O and DMF.
