Abstract

PURPOSE:To obtain a highly permeable porous membrane having improved heat and solvent resistance, by immersing a membrane, formed from a vinylidene fluoride resin solution containing plural types of surface-active substances, in a non- solvent to remove the solvent and substances. CONSTITUTION:5-30wt% solution comprising (A) a vinylidene fluoride resin, (B) a solvent, e.g. dimethylformamide, for (A), and (C) two or more types of surface-active substances, preferably comprising is one or more nonionic (poly)alkylene glycols, formed into a membrane by the casting method. The resulting membrane is immersed in a non-solvent, e.g. water, to give the desired membrane free the solvent and substances. Hollow fiber may be used as the membrane.
