摘要：
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.
