Abstract: A porous asymmetric membrane comprises a hydrophobic polymer comprising a poly(phenylene ether) or poly(phenylene ether) copolymer; and a polymer additive. A separation module can be fabricated from the porous asymmetric membrane. A method of forming the porous asymmetric membrane comprises: dissolving a hydrophobic polymer comprising a poly(phenylene ether) or poly(phenylene ether) copolymer and, a polymer additive in a water-miscible polar aprotic solvent to form a porous asymmetric membrane-forming composition; and phase-inverting the porous asymmetric membrane forming-composition in a first non-solvent composition to form the porous asymmetric membrane. The polymer additive comprises hydrophilic functional groups, copolymerized hydrophilic monomers, or blocks of hydrophilic monomer repeat units. For example, the polymer additive can comprise a hydrophilic polymer or amphiphilic polymer. The porous asymmetric membrane can be a flat membrane or hollow fiber.

Abstract: An method of making a porous asymmetric membrane involves dissolving a poly(phenylene ether), poly(phenylene ether) copolymer, polyethersulfone, polysulfone, polyphenylsulfone, polyimide, polyetherimide, polyvinylidene fluoride, or a combination thereof in a water-miscible polar aprotic solvent to provide a membrane-forming composition; and phase-inverting the membrane-forming composition in a first non-solvent composition composed of water, a water-miscible polar aprotic solvent, or a mixture thereof, and a polymer additive dissolved in the first non-solvent composition. The method can be a method of making a hollow fiber by coextrusion through a spinneret having an annulus and a bore, including coextruding the membrane-forming composition through the annulus, and the first non-solvent composition through the bore, into a second non-solvent composition composed of water, a water-miscible polar aprotic solvent, or a mixture thereof to form the hollow fiber.

Abstract: An amphiphilic block copolymer comprises a poly(phenylene ether) block or a poly(phenylene ether) copolymer block and a hydrophilic block or graft. A method of making the amphiphilic block copolymer comprises polymerization of a hydrophilic ethylenically unsaturated monomer in the presence of poly(phenylene ether) or a poly(phenylene ether) copolymer to make the amphiphilic block copolymer. A porous asymmetric membrane comprises a poly(phenylene ether) or poly(phenylene ether) copolymer, and the amphiphilic block copolymer comprising a poly(phenylene ether) block or a poly(phenylene ether) copolymer block, and a hydrophilic block or graft. The porous asymmetric membrane is made by phase-inversion of a dope solution of the poly(phenylene ether) or poly(phenylene ether) copolymer and the amphiphilic block copolymer in a coagulation bath.
