Polysulfone hollow fiber membranes were fabricated by a dry/wet spinning process, with N-methyl pyrrolidinone (NMP) and water as solvent and coagulant, respectively. The results indicate that air-gap length and ambient humidity have dramatic effect on the membrane morphology. Macrovoids in the membr

## Abstract Several kinds of chloromethyl polysulfones (CMPSF) with different chlorinity and reactive groups were synthesized by FriedelβCrafts reaction, which could be utilized as reactively matrix membrane materials. The CMPSF hollow matrix membranes were prepared with phase inversion by utilizat
## Abstract The development of porous polysulfone hollow fibers and the spinning process used are discussed. An analysis is given of the spinning parameters which determine fiber mechanical properties and permeability. Hollow fibers were prepared which display high modulus and high tensile strength
