Sorption and permeation of CO 2 were investigated by using synthetic polymer membranes having pyridine moiety or pyridine–Cu(II) complex group as a fixed carrier. The solubility data for CO 2 were interpreted by the dual sorption model, Henry's law plus Langmuir‐type adsorption. The permeation results of CO 2 through the present membranes containing pyridine moiety were analyzed in terms of the partial immobilization model, while the solubilities and permeablities of O 2 and N 2 obeyed Henry's law. Permselectivity of the present membrane for CO 2 was achieved. These results were explained by the acid‐base interaction between CO 2 molecules and fixed carrier in the present membrane.
