Abstract: A polymeric membrane made of a polyimide polymer or copolymer essentially consisting of repeating units of dianhydride-derived units and diamine-derived units. At least some of the dianhydride-derived units are derived from 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane (6FDA). At least some of the diamine-derived units are derived from 2,5-diethyl-6-methyl-1,3-diamino benzene (DETDA). The balance of the diamine-derived units are derived from a diamino benzene ring with a carboxylic acid substituent.
