Abstract: PTMSP membranes were modified by plasma technigue in the presence of hexamethyldisiloxane.The oxygen permeation rate Po2 and oxygen-nitrogen separation coefficient αO2/N2 of the modified membranes were 1590 barrer and 3.16, respectively.

Key words: PTMSP, plasma modification, oxygen-nitrogen permselectivity, disiloxane
