| Abstract: | Poly[1-(trimethylsilyl)-1-propyne] membranes were modified with fluorine gas.The fluorinated membranes exhibited good gas permeation properties and a significant in-crease in gas selectivity over the unfluorinated PTMSP membranes.The oxygen-nitrogenseparation coefficient increased from 1. 5 to 4.75,the oxygen permeation coefficientsdecreased from 8600 to 370 barrier, and the constancy of gas permeabitily of the mem-branes was improved. |

| Keywords: | polytrimethylsilylpropyne modification by fluorine oxygen nitrogen permeability |
