✦ Synopsis

Inverse gas chromatography has been used to characterize the interaction of polyetherpolyurethane with 17 solvents of various polarities at I00-150Β°C. The specific retention volume (V~) measured for each probe was used to calculate various thermodynamic parameters and properties at infinite dilution, viz. Z, Z *, X~2, AHS, AH~, AG ~ and TASk. The dependencies on temperature and nature of the solvent are discussed. Also we have calculated the solubility parameter of the polymer using the method of Guillet and Dipaola-Baranyi at the above temperatures and also at 25Β°C.

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
