Activity coefficients and interaction parameters determined from vapor sorption measurements are reported for chloroform and dichloromethane at infinite dilution in poly(dimethylsiloxane) (PDMS) at 303 K. These agree, within experimental error, with values obtained previously by gas–liquid chromatography (GLC) on the same polymer sample. The method developed by DiPaola-Baranyi and Guillet to evaluate a solubility parameter for a polymer stationary phase from GLC measurements has been applied successfully to the vapor sorption results for various solutes in PDMS and a value of the PDMS solubility parameter determined.
