ABSTRACT:
A porous membrane, such as a microporous or ultrafiltration membrane, is formed from a solution of a polysulfone and a free radical polymerizable monomer exposed to ultraviolet light to form a blend of the polysulfone and copolymers of polysulfone activation products and polymerized monomer having polymer segments covalently bonded to each other. The solution is separated into two phases including a porous solid phase comprising the membrane.
