Effects of Temperature and Solvent Composition on the Intrinsic Viscosity of Polyvinyl Butyral in Ethanol / Water Solutions

The self-diffusion coefficients of Na+, Cl- and I- in methanol-water solutions at 35 ± 0.01 °C have been measured in their dependence on the salt molarity in the range 1 · 10-4- 1 · 10-2 mol dm -3. The ionic self-diffusion coefficients in infinitely diluted solutions have been computed. The influence of the solvent composition on the solvation of the ions is discussed. A preferential hydration of Na+, Cl- and I- ions in water-methanol mixtures has been found.

Long Chain

The intrinsic viscosity of a sample of GR–S has been measured, at temperatures ranging from 0° to 65 °C., in several solvents made progressively 'poorer' (to the point of precipitation) by the addition of nonsolvent. The results afford strong evidence in support of the theory (Flory; Alfrey, Bartovics, and Mark) that intrinsic viscosity is very sensitive to the shape assumed by a flexible long-chain molecule in solution and that this shape varies with the nature of the solvent and with the temperature. Measurements with various systems of the type GR–S–solvent–nonsolvent indicate that the intrinsic viscosity at the precipitation point is the same with different nonsolvents and, to a first approximation, with different solvents. This intrinsic viscosity is, moreover, independent of temperature.
