Abstract

PURPOSE:To provide a less amount of homopolymer content, and make the promotion of extension for life of the cell, by processing a grafting copolymerization to vinyl monomer, after irradiating a radiant ray to the thermo-plastic film under a presence of oxygen. CONSTITUTION:For thermo-plastic films of polyethylene, polypropylene, fluorine system polymer, etc., by processing a radiant ray irradiating treatment like electron beam gamma line in an oxygen ambience of, for instance, more than oxygen density 21% by volume, a hydroperoxide or peroxide is produced. Subsequently with a contact made of a vinyl monomer, consisting of unsaturated carbonic acids like acrylic acid, methacrylic acid, etc. capable of providing a conductivity to the film, in the method of immersion heating, te vinyl monomer is processed grafting copolymerization. In such way, a separator, with a less amount of homopolymer content and constant grafting rate, is made stably obtained, thus can be prolonged a life of the cell.
