Summary:PURPOSE:To improve alkali resistance and alkali oxidation resistance, etc. by machining a mixture of polyolefin resin, extractable organic material, inorganic fine powder, and non-ion surface active agent into a thin film and subjecting it to extracting treatment. CONSTITUTION:To 100pts.wt. of synthetic resin made of polyolefin resin or added with hydrophilic resin, about 50-250pts.wt. of extractable organic material such as di-2-ethyl hexyl phthalate, about 100-350pts.wt. of inorganic such as titanium oxide, and a proper quantity of non-ion surface active agent are added and kneaded. After this mixture is machined into a thin film shape, the extractable organic material is subjected to extracting treatment to form a separator by using a proper organic solvent. This separator for an alkaline cell has alkali resistance, alkali oxidation resistance, and heat resistance, and is excellent in the electric and mechanical performance, thereby the cell life is improved when it is assembled into a cell.
