Abstract
A composite of a rigid, glassy, permeable membrane of a silyl or germyl-containing polyacetylene and a thin surface layer of a plasma polymerized monomer having pendant nitrogen heterocycles is provided; the composite has high flux and selectivity and is particularly useful for separating gas mixtures containing at least two components having different permeabilities through the composite structure.
