Abstract

Six samples of poly(2-deoxy-2-methacryloylamino-D-glucose) were prepared by free-radical polymerization of the monomer. The molecular properties of the homologous series obtained were studied in three solvents, 0.2 M NaCl, 0.1 M Na2SO4, and salt-free water, by viscometry and static and dynamic light scattering. The Mark-Kuhn-Houwink relationships were obtained. The poly(vinyl saccharide) studied, despite the presence of bulky pendant substituents, is a typical flexible-chain polymer with the Kuhn segment length of 20 ± 3 Å. In aqueous salt systems, poly(2-deoxy-2-methacryloylamino-D-glucose), which is not a polyelectrolyte, nevertheless demonstrates the dependence of the hydrodynamic size of the molecules on the solvent composition. The SO 4 2− ions make the polymer molecules more compact, whereas Cl ions present in aqueous solution lead to its expanding. Salt additions affect the thermodynamic quality of the polymer-solvent system.
