SOLVENT-RESISTANT SEPARATION MEMBRANE AND METHOD FOR PRODUCING SOLVENT-RESISTANT SEPARATION MEMBRANE

摘要

The purpose of the present invention is to provide a membrane that can be used for liquid mixtures including organic solvents, and that has excellent separation capability. This solvent-resistant separation membrane is provided with a porous layer containing an infusible polymer, wherein the size of the crystallites of the infusible polymer is at least 10.0 nm, as measured by X-ray diffraction.
