Abstract
The isosteric characteristics for the retention of water and isopropanol on the polyvinyltrimethylsilane (PVTMS) sorbent were calculated from data obt ained by nonlinear gas chromatography over the temperature range 26-150 deg rees C. The temperatures of the structural transitions in the polymer and t he degrees of filling at which these transitions occurred were determined. The mechanisms of the sorption of water and isopropanol were found to be de pendent on the degree of filling and temperature.
