摘要
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, with different porosity parameters were synthesized by suspension copolymerization and modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine, EDA. Inverse gas chromatography at infinite dilution was used for the determination of adsorption properties of PGME, and copolymer modified with ethylene diamine, PGME-en. Thermodynamic parameters of adsorption, dispersive components of the surface free energies, and the S, acid/base constants for the copolymer samples were calculated. The calculated dispersive surface energy values, gamma(d)(S), for PGME and PGME-en are comparable with the literature data for nonconductive polymers. (c) 2005 Elsevier Ltd. All rights reserved.
