Abstract2-Oligodimethylsiloxanyl substituted 5-norbornene-2-carbonitriles and carboxylates were synthesized from 5-norbornene-2-carbonitrile and methyl 5-norbornene-2-carboxylate by metalation at the 2-position followed by reaction with monochloro functionalized oligodimethylsiloxane. Polymers were obtained by the ring-opening polymerization of the monomers by a metathesis catalyst. Permeation of oxygen through the polymer films was highly selective over nitrogen. The diffusion coefficient was shown to play the principal role in the permeation.
