Abstract
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. .
U okviru rada prikazane su mogućnosti korišćenja inverzne gasne hromatografije (IGC) za karakterizaciju polimera. Umreženi makroporozni kopolimer glicidilmetakrilata, GMA, i etilenglikoldimetakrilata, EGDMA, poli (GMA-co-EGDMA) sintetizovan je suspenzionom kopolimerizacijom, a zatim modifikovan reakcijom sa etilendiaminom. Uzorcima polaznog i modifikovanog kopolimera, poli(GMA-co-EGDMA)-en, su pri nultoj prekrivenosti određeni termodinamički parametri adsorpcije, disperzivna komponenta slobodne površinske energije i kiselo/bazna svojstva.
