## Abstract 6FDAβMDAβbased polyimides were synthesized from a oneβstep polycondensation of 6FDA and MDA with other diamines and dianhydrides. The polyimides were characterized by GPC, FTβIR and NMR, and dense membranes were prepared from their solutions for gas separation and pervaporation. Gas sep
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
