摘要：
The CO 2 absorption capacity of the polymers from ionic liquids which was much higher than room temperature ionic liquid was discussed. The polymers poly[1-(4-vinylbenzyl)-3-butylimidazolium tetrafluoroborate] (PVBIT), poly[(1-(4-vinylbenzyl)-3-butylimidazolium hexafluorophosphate] (PVBIH) and poly[2-(1-butylimidazolium-3-yl)ethyl methacrylate tetrafluoroborate] (PBIMT) were prepared from their corresponding ionic liquid monomers. It took four minutes for PVBIT and PVBIH and three minutes for PBIMT to reach their 90% sorption capacities. Analysis shows that the CO 2 absorption capacity of the polymers is due to the interaction of the imidazolium tetrafluoroborate moiety with CO 2.
