Previously undescribed norbornene monomer 3,3,4-trifluoro-4-perfluorohexyltricyclononene-7 is synthesized by the [2+2+2] cycloaddition reaction. The monomer is involved in the ring-opening polymerization metathesis in the presence of the first-generation Grubbs catalyst to give rise to the amorphous, glassy unsaturated polymer. The gas-transport properties of the metathesis polymer is studied, the gas permeability and diffusion coefficients for a wide range of gases (He, H2, O2, N2, CO2, CH4) are determined, and the solubility coefficients of gases in this polymer are calculated.
