Abstract: The method is for manufacturing the porous polyolephin seperation film from the solution mixed with the polyolephine(polyetylene or polyprophilene) and a diluent(a natural soy bean oil, a olein acid or a renolein acid). The method comprises a step of forming the porous seperation film by spraying the mixed solution; a step of solidifying the film by use of the solidification solvent and extracting the diluent; a step of evaporating the remaining diluent and the extraction solvent.
