Inverse gas chromatography has been used to characterize the interaction of polyetherpolyurethane with 17 solvents of various polarities at I00-150°C. The specific retention volume (V~) measured for each probe was used to calculate various thermodynamic parameters and properties at infinite dilution

Inverse gas chromatography (IGC) is a versatile tool for the characterization of porous solids. IGC at finite dilution has historically been used for isotherm measurements because of fast equilibration times. A combination of IGC with a flash thermodesorption method allows the separation of micropor
## Abstract Polymeric monoliths of different polymeric natures and different degrees of cross‐linking were prepared in capillaries of inner diameter 100 μm. The properties of the monoliths prepared were investigated by means of inverse gas chromatography. Solubility coefficient __S__, Flory–Huggins
