Several polymer membranes based on vinylimidazolium monomerswere fabricated and tested for CO2 permeability and permeabilityselectivity.  Vinylimidazolium-basedroom-temperature ionic liquid (RTIL) monomers were synthesized and possessedchemical functionalities specifically aimed at enhancing CO2 permeabilityselectivity and/or CO2 permeability. These monomers were photopolymerized on a porous polyethersulfonesupport between two glass plates to afford 140-150 �m thick, mechanicallystable poly(RTIL) membranes.  CO2permeability as well as CO2/N2 and CO2/CH4permeability selectivity for the poly(RTIL) membranes were obtained with a timelag apparatus and are presented on Robeson Plots.  CO2 diffusivity and solubility dataof the poly(RTIL)s are also presented. The CO2 separation performance of the vinylimidazoliumpoly(RTIL)s studied here are compared to previously studied poly(RTIL)s as wellas other dense polymer membranes.
