摘要
Inverse gas chromatography has been used to characterize the interaction of polyetherpolyurethane with 17 solvents of various polarities at 100-150-degrees-C. The specific retention volume (V(g)0) measured for each probe was used to calculate various thermodynamic parameters and properties at infinite dilution, viz. chi, chi*, X12, DELTAH-1S, DELTAH-1infinity, DELTAG1infinity and TDELTAS1infinity. 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 25-degrees-C.
