Increase in gas separation selectivity during physical aging of OH-containing polyimide
Gas transport characteristics of new polyimide (PI) containing hydroxyl groups in the diamine moiety for seven permanent gases have been investigated: H 2 , He, O 2 , N 2 , CO, CO 2 , and CH 4 . Changes in the gas separation properties of polyimide during its physical aging over a year have been exp...
