Microprous polyethersulfone membranes with asymmetric structure were prepared by phase inversion method. The influence of solvent, coagulation agent and additions of polyethylene glycols with various molecular weights was studied. The membrane morphology was characterized by scanning electron microscopy and their hydrodynamic properties by solvent permeation and standard system filtering. The results recommend these membranes for utilization in micro- and ultra- filtration.
