摘要

The preferential interaction of polyvinylacetate (PVA) with one of the solvent components in water-ethanol mixtures has been investigated by the method of equilibrium dialysis, evaluated by differential refractometry. It has been found that at a 1:1 molar ratio of water-ethanol there occurs an inversion point of preferential solvation. The overall solvation was determined from intrinsic viscosity and equilibrium swelling measurements. Its plot versus the composition of the binary solvent has a maximum that practically coincides with the inversion point of the preferential solvation. These results are compared with those obtained from pervaporation studies carried out on PVA-membranes in the same solvent system, and they are discussed in terms of the existence of special interaction phenomena due to hydrogen bonding effects. It can be concluded that for the system investigated preferential solvation parameters help to understand, but do not necessarily predict, membrane permselectivity. 12 refs., 14 figs., 2 tabs.
