Abstract

The thermodynamic properties of the glassy polyvinyltrimethylsilane (PVTMS) have been investigated by means of reverse gas chromatography. Values of the Flory-Huggins parameter in the range 25–230° were determined for systems of the types: polyvinyltrimethylsilane-hydrocarbons and polyvinyltrimethylsilane-alcohols. As the temperature rises the hydrocarbons become θ solvents for polyvinyltrimethylsilane, while the alcohols become good solvents.
