TY - JOUR TI - Application of inverse gas chromatography for polymer characterization AU - Nastasović Aleksandra B. AU - Onjia Antonije E. AU - Milonjić Slobodan K. AU - Jovanović Slobodan M. JN - Hemijska industrija PY - 2007 VL - 61 IS - 6 SP - 342 EP - 349 PT- Article AB- The possibility of polymer characterization by inverse gas chromatography (IGC) was illustrated with the study of sorption properties of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, synthesized by suspension copolymerization, and copolymer modified with ethylene diamine, PGME-en. The data collected from IGC experiments at infinite dilution are used for the calculation of the thermodynamic parameters of adsorption, dispersive components of the surface free energies, and the acid/base constants. .
