Abstract: Polyimide membranes are provided that provide extremely high permeability. The polyimides do not contain carbonyl or sulfonyl functional groups. These membranes are useful in separating gases including the separation of gas pairs including carbon dioxide/methane, hydrogen/methane and propylene/propane as well as other gas mixtures. The membrane selectivity can be adjusted by exposure to ultraviolet light.

Abstract: A copolyimide membrane is provided by the present invention that is effective in separating olefins and paraffins. The membrane with very high selectivity and permeability in the present invention is used in a process for separating olefins from a mixture of olefins and paraffins, the process comprising providing a copolyimide membrane with very high selectivity and high permeability described in the present invention which is permeable to said olefin; (b) contacting the olefin/paraffin mixture on one side of the copolyimide membrane with very high selectivity and high permeability described in the present invention to cause the olefin to permeate the membrane; and (c) removing from the opposite side of the membrane a permeate gas composition comprising a portion of the olefin which permeated through the membrane. Ethylene, propylene, butene, or pentene is separated from ethane, propane, butane, or pentane, respectively with up to 99 mole % olefin content in the permeate.
