Investigation of Gas Permeability Property of Six Polyetherimide Membranes

Gas permeabilities and selectivies for gas pairs H_2/N_2 CO_2/N_2 andO_2/N_2 through a series of aromatic polyetherimids, which were prepared from twodifferent dianhydrides and three distinct diamines, have been investigated. Systematicvariations in chemi
