Annotation	This study confirms the positive effect of ionic liquid content in neat polymer on mix gas (CO2/H2) separation. The sorption of CO2 increases with increasing content of [emim][dca] in PVA polymer membranes. The sorption of H2 was negligible in all measured membranes even with highest content of [emim][dca] in PVA. All single gas permeation experiments clearly show increasing permeability of CO2 and H2 with increasing content of ionic liquid in studied polymer. During separation of both gasses, the solution diffusion mechanism is applied. Based on these results we can state that with higher content of [emim][dca] in PVA permeability of both gasses and also ideal selectivity increases. This observation shows a potential of IL where is higher sorption of CO2 than in polymer as good separation medium for CO2/H2 separation.
