Abstract: Microporous phenolic polyether membranes are provided having utility in electricity generators, devices for the oxygenation of the blood, degassing of solution, ultrafiltration and the like. These membranes comprise a film of a phenolic polyether which has, on each of its faces, pores of diameter between about 0.1 and 25 Mu , at least some of these pores passing through the entire thickness of the membrane. They can be obtained by: A. FORMING A SOLUTION OF THE PHENOLIC POLYETHER WITH A SOLVENT AND A NON-SOLVENT FOR THIS POLYMER, THE SOLVENT AND NON-SOLVENT BEING MISCIBLE WITH ONE ANOTHER, B. CASTING THIS SOLUTION ON A TEMPORARY SUPPORT, C. LEAVING THE POLYMER LAYER ON THE SUPPORT IN AIR FOR ABOUT 1 SECOND TO 3 MINUTES, AT A TEMPERATURE OF BETWEEN 10*C and the boiling point of the most volatile constituent of the solution, D. IMMERSING THE POLYMER LAYER, STILL ON ITS SUPPORT, IN A COAGULATION BATH, AND E. SEPARATING THE MEMBRANE FROM THE SUPPORT AND DRYING IT.
