ABSTRACT:
Disclosed are semipermeable fluid separation membranes prepared from polyaromatic polymers including aromatic repeat units of which at least five mole percent are substituted by moieties having ethylenically unsaturated carbon bonds wherein the polymer is crosslinked through carbon bonds between the ethylenically unsaturated moieties. The invented membranes have enhanced durability yet retain very high fluid, especially gas, permeability.
