Abstract: An asymmetric membrane having a substantially non-porous surface layer is made by a method including: dissolving a poly(phenylene ether) copolymer in a solvent mixture including a first solvent and a second solvent to provide a membrane-forming composition; and phase-inverting the membrane forming composition in a first non-solvent to form the membrane comprising a substantially non-porous surface layer. The first solvent is a water-miscible polar aprotic solvent, and the second solvent is a polar solvent having two to eight carbon atoms.

Abstract: A porous membrane made from a poly(phenylene ether) copolymer has at least one of: a molecular weight cut off of less than 40 kilodaltons or a surface pore size of 0.001 to 0.1 micrometers. The porous membrane is made by dissolving the poly(phenylene ether) copolymer in a water-miscible polar aprotic solvent to form a porous membrane-forming composition; and phase-inverting the porous asymmetric membrane forming-composition in a first non-solvent composition to form the porous mem-brane. The porous membrane can be in the form of a sheet or a hollow fiber, and can be fabricated into separation modules.

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.

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.
