POLYSULFONE POLYMERS AND MEMBRANES FOR REVERSE OSMOSIS, NANOFILTRATION AND ULTRAFILTRATION
摘要
<p>The invention provides modified polysulfones substituted in one or more of the phenyl rings by functional groups and membranes composed of the modified polysulfones. Also provided are methods for the preparation of monodispersed nanoporous polymeric membranes. The membranes are useful for reverse osmosis, nanofiltration, and ultrafiltration, particularly for purification of water.</p>
