dc.description.abstractPolyamide and polypyrrolone membranes for fluid separation having desirable permeabilities, solubilities, diffusivities,, high glass transition temperatures and large fractional free volumes. In particular, the membranes are the polyamide and polypyrrolone forms of hexafluoroisopropylidene-bisphthalic anhydride polymerized with 3,3',4,4' tetraaminodiphenylisopropylidene (6FDA-TADPIP) and polymerized with hexafluorotetraamine (6FDA-6FTA). Fluid separation membranes made from these polymers are described as well as a method of separating fluids using these membranes. Pure gas permeabilities and permeabilities with gas feed mixtures using the fluid separation membranes for feed pressures up to 900 psia indicate desirable permeability and no plasticization effects.
