ABSTRACT:
The present invention provides for gas separation membranes with superior gas transport properties made from a blend of certain polymers. In particular, certain alkyl substituted aromatic polyimides, polyamides or polyamide-imides are blended with certain aromatic polyimides to provide a gas separation membrane with superior productivity and good selectivity.
