Abstract

Abstract Polyethyleneoxide(PEO)-containing copolyimides having microphase separated structure have high permeability to CO2 and high permselectivity for CO2 over N2. The permeation occurs through soft segment phase of PEO and the high permselectivity is ascribed to high solubility selectivity.
