Method for preparing a membrane of a film-forming non-sulfonated sulfone polymer |
| abstract |
Sulfone polymer ultrafiltration membranes with remarkably high permeability to solvent at low pressure combined with excellent retention of low molecular weight macromolecules and sharp molecular weight cutoff are prepared by casting a sheet of said polymer dissolved in a specified solvent (hexamethylphosphoramide). evaporating a portion of the solvent from the sheet and immersing said sheet in a gelation liquid therefore. |
