ABSTRACT:
The present invention is a modified polymeric membrane having improved selectivity for separating gas mixtures. The membrane comprises a silyl substituted polyacetylene polymer to which has been added 5 to 50 wt. % of an additive which is miscible with the polymer, has a boiling point >300.degree. C. at atmospheric pressure, is soluble in a common solvent for the polymer and increases the selectivity ratio of O.sub.2 /N.sub.2 by at least 15% over the polymer without the additive.
