Poly (ethylene glycol) (PEG) is widely used as CO<sub>2</sub> separation membrane materials because it has high affinity for CO<sub>2</sub> due to dipole-quadrupole interactions. However, PEG has drawbacks such as low permeability and difficulty of manufacturing due to its high crystallinity and low physical properties. In order to solve these problems, researches have blended polymers with high physical properties and prepared crosslinked polymers using a crosslinking agent. In case of the crosslinked polymers, the degree of crystallinity can be reduced because the added agent interferes with the regular arrangement of polymer chains. Furthermore, the mechanical strength can be improved by adjusting the crosslinking density. Therefore, in this study, PEGbased crosslinked membranes were prepared under UV irradiation. The prepared membranes were characterized by FT-IR, XRD, TGA and DSC. The permeability and selectivity of the membranes for CO<sub>2</sub>, CO, and N<sub>2</sub> were investigated using time-lag apparatus.
