ABSTRACT:
A water wettable permselective membrane for use in hemodialysis, ultrafiltration and microfiltration applications and a device containing the same are provided. The membrane having the above properties comprises a hydrophobic-base polymer, such as a polysulfone or polyethersulfone polymer, and a block copolymer additive wherein one of the blocks of the copolymer additive is a hydrophilic polymer and the other block is a hydrophobic polymer that is analogous in structure to the hydrophobic-base polymer.
