Porous blended polymer (polyethersulfone, phenoxy resin) filtration membranes are provided which are hydrophobic, strong, have a lowered melt temperature, and are useful for filtering macromolecules or particles from fluids. Thus, blending polyethersulfone with phenoxy resin in a porous polymer membrane formulation importantly results in a stronger and lower melting membrane than a comparable membrane made only with polyethersulfone polymer. |
