Gas separation membranes from polymers containing a hydrocarbon backbone and pendant (hydrocarbylamido)alkyl ester moieties

摘要

The invention relates to improved gas separation membranes fabricated from cyclic iminoether modified alpha-olefin/carboxylic acid copolymers. The modified membranes possess improved gas selectivities and/or permeabilities over the unmodified membranes. The membranes may be used to separate gas mixtures containing such gases as oxygen, nitrogen, methane, and carbon dioxide.
