説明
Novel poly(vinyl ether)s with tetraethylene glycol and methacrylate side groups [poly(TetraEGMVE-VEEM)] were synthesized by the copolymerization of TetraEGMVE with VEEM. The free-standing membranes of poly(TetraEGMVE-VEEM)s were prepared by thermal crosslinking between the methacrylate units. Membranes of poly(TetraEGMVE-VEEM) with 2:1 composition ratio showed high CO2 permeability and CO2/N2 selectivity, whose PCO2 and PCO2/PN2 were 250 barrer and 52, respectively. The PCO2 of membranes of poly(TetraEGMVE-VEEM) with 4:1 composition ratio was 320 barrer, which is larger than that with 2:1 composition ratio. This difference is caused by the number of crosslinking points in the polymer matrix. The CO2 permeability of poly(TetraEGMVE-VEEM) is higher than that of poly(vinyl ether) having diethylene glycols as a side chain. This high permeability originates from the high diffusivity of CO2 in the membranes.
