Abstract

Abstract The viscosity and osmotic pressure of a fraction of poly-2-vinylpyridine have been measured in various solvents, and the parameters concerning the solubility of this polymer, that is, the osmotic second virial coefficient, A2, the polymer-solvent interaction parameter, μ, and the solubility parameter, δ2, have been obtained. From the values of these parameters, the following conclusions have been obtained: poly-2-vinylpyridine has a solubility parameter of ca. 10.4 (cal./cc.)1⁄2 and acts as an electron donor. As a result of the specific interaction between a solvent and the pyridine nitrogen of this polymer, the solvent power is greater in an acidic solvent and smaller in a basic than would be expected from the solubility parameter alone. An especially strong interaction between poly-2-vinylpyridine and aliphatic alcohols, chloroform and nitroethane has been observed and its nature has been discussed.
