ABSTRACT:
A polysulfone composition 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 activated polysulfone and polymerized monomer having polymer segments covalently bonded to each other. The blend is separated from solvent of the solution to form a solid comprising the blend throughout its bulk matrix.
