Four types of new silicon-based graft blended polymers were developed and drawn to thin film composite membranes on high flux microporous polyetherimide support. The membranes and a 1 μm PDMS membrane as a standard were tested for the flux of the gases N2, O2, Ar, CH4, CO2, CH3Cl, C2H5Cl, C2H6, and n-C4H10 and the vapors methanol (MeOH), t-butyl methyl ether (MTBE), 1, 1, 1-trichloroethane (Cl3Eth), 1, 1, 2-trichlorofluoroethane (Cl3F3Eth), and n-hexane (n-C6H14). Methanol/argon mixtures were used to check the validity of the calculated selectivities. The results show higher performance for the newly developed membranes.
