ABSTRACT:
Processes utilizing polyphosphazene membranes for separating polar fluids from non-polar fluids are disclosed. Fluid separation membranes comprised of polyphosphazenes having halogenated side groups are disclosed as exhibiting effective preferential selectivity and permeabilities for polar fluids relative to non-polar fluids contained in feedstream mixtures. The polyphosphazenes are in general rubbery polymers having attractive fluids transport properties and improved thermal and chemical stability.
