Abstract: Po1y[1-(trimethy1si1yl)-1-propyne](PTMSP) of higher molecular weight was synthesized by cationic polymerization in solution. It has a structurc of [-C(Me)=C(SiMe3)-). It is an amorphous,soluble solid.The permeability to oxygen and selecfivity of O2/N2 of PTMSP membrane are reported after various modification.

Key words: PTMSP, membrane, modification, gas seperaion
