초록

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.

A gas separation membrane comprising a semipermeable membrane fabricated from a polymer containing a hydrocarbon backbone and pendant (hydrocarbylamido)alkyl ester moieties. A method of separating gases comprising the steps of (a) contacting with a feed gas mixture under pressure one side of a semipermeable membrane comprising a membrane fabricated from a polymer containing a hydrocarbon backbone and pendant (hydrocarbylamido)alkyl ester moieties; (b) maintaining a pressure differential across the membrane under conditions such that a component(s) of the...
