“…In the case of gases and water, it is negative, so it can also be regarded as a measure of the hydrophobicity of the phase.The coefficients c, e, s, a, b, and l were obtained by fitting the experimental values of the quantity SP (in our case, the retention volume). In the literature, [11][12][13][14] applications of solvation theory for the characterization of polymer-solvent interactions have been extensively reported.

Infinite-Dilution Activity Coefficients of Volatile Organic Compounds in Cyclic Olefin Copolymers

et al. 2011

View full text Add to dashboard Cite

Infinite-dilution activity coefficients for nine classes of volatile organic compounds (paraffins, olefins, cycloparaffins, aromatics, ketones, nitriles, alcohols, esters, and chlorocompounds) in a series of four cyclic olefin copolymers were determined using an inverse gas chromatography technique with a packed column. Abraham’s equation of solvation was used for the evaluation of the different types of interactions between the solvents and polymers. The results are compared with the activity coefficients at infinite dilution obtained for other polymers of similar use
