文摘

Three new co-polyimide structures containing a sulfone group are synthesized. The CO2/CH4 permselectivity of the co-polyimides are as high as 47–52. Permeabilities agree reasonably well with predictions of group contribution method. Sulfone group is the most preferential sorption site enhancing CO2 sorption.
