Abstract
A new oxygen/nitrogen separation membrane based on a polynorbornene with tosylate side chain group was synthesized using well-defined vinylidene ruthenium catalysts. The permeability, separation factor, diffusion and solubility coefficients of a polynorbornene membrane were studied. The introduction of tosylate group into the five-membered ring of the polynorbornene main chain results in increase of Tg and significant improvement in selectivity for O2/N2.
