ABSTRACT:
A photochemical grafting process permits the attachment of free radically polymerizable monomers to the surface of aryl polysulfone membranes. The process, which does not use sensitizers, results in membrane compositions which can be used for ultrafiltration and microfiltration membranes and which exhibit low or non-fouling characteristics.
