Description
Summary:Reversed gas chromatography was used to study thermodynamics of sorption of C 2-C 3 hydrocarbons by glassy polyvinyltrimethylsilane and high-elastic PDMS with coordination unsaturated nickel acetylacetonate additives. The solubility factor of acetylene and methylacetylene increases more sharply than for other hydrocarbons, for which sorption parameters show non-specific variation. It was found that excess functions of mixing hydrocarbons depend on their molar volume.
