Abstract:
Porous blended hydrophilic copolymer (polyethersulfone resin, poly-2-oxazoline resin, and polyvinylpyrrolidone resin) microporous membranes are provided which are useful for filtering macromolecules or particles from fluids. The invention also concerns a process for filtering matter from a fluid, employing the membranes.
