Carbon molecular sieve (CMS) membranes containing alkali metal ions (Li + , Na + , and K + ) were prepared by the pyrolysis of metal-substituted sulfonated polyimide (M-SPI) precursors. We have determined the effect of substituted metal ions in the polymeric precursor on the gas separation performan
Carbon molecular sieve (CMS) membranes were prepared by pyrolysis of polyimides containing carboxylic acid groups, in order to investigate their permeation properties for He, CO 2 , O 2 and N 2 . The polyimides were synthesized with a varying number of carboxylic acid groups in the diamine. Wide-ang
