Although the dilution ratio-that indicates the volume fraction of non-solvent in the total solution at the precipitation point, to which a polymer Solution of a standard concentration is brought by the addition of non-solvent-has been believed to be applicable as a relative measure of the solvent power of the solvent used, there exists much experimental evidence against it. The reason why the dilution ratio cannot be, for a polymer, a relative measure of evaluating solvent power has been explained from Huggins-Flory's theory of the solubility of polymer, and a method of correcting the measured dilution ratio for the aim of making it applicable as a measure of solvent power has been proposed. Experimental results on nitrocellulose and polybutene have shown that, in each case of these polymers, the greater the dilution ratio corrected by that method, the higher the value of [η]/V^2 is, where [η] is the intrinsic viscosity, V in the molar volume of solvent and further that the relation between them can almost practically be represented by a smooth curve. For a given polymer, the corrected dilution ratio can, therefore, be accepted as a relative measure of solvent power, since [η]/V^2 is, as shown in the previous paper, applicable as such a measure. |
