Adsorption properties of two laboratory synthesized macroporous copolymers based on methyl and glycidyl methacrylate were investigated by inverse gas chromatography. Retentions of 12 organic compounds were measured in the temperature range from 65 to 80 degrees C. The gas/solid partition coefficients and the related thermodynamic function of adsorption at zero surface coverage were determined. The dispersive component of free surface energy of both copolymers, at investigated temperatures, was also calculated. The obtained experimental data were used to explain the polymer-adsorbate interaction. (C) 2000 Elsevier Science B.V. All rights reserved.
