Polymeric membranes of Styrene-Ethylene-Butylene-Styrene block copolymer (SEBS) were obtained by sulfonation (0 and 2 hours) and addition of piperazine (PZ) (0, 15, 20% w/w). The permeability of the CO2 through the membranes and the selectivity with respect to the N2 were determined. The influence of physicalchemical properties as water uptake and porosity on the transport of CO2 through the membranes was also analyzed. Permeation properties was improved with sulfonation and addition of
