Abstract

PURPOSE:To produce a separator having good producibility and excellent properties through such process that ionization radiant ray is irradiated, in atmospheric environment and the like, on a synthetic resin film which shall be dipped in acylic acid solution etc. to effect graft polymerization at a low temperature. CONSTITUTION:Ionization radiant ray is irradiated onto a synthetic resin film having thickness of 50-150mum in air or in oxygen atmosphere. Next, the irradiated film is dipped in one or both of acrylic acid solution and methacrylic acid solution to effect graft polymerization at a low temperature. It is preferable to employ 10- 60wt% as the monomer concentration of the acrylic or methacrylic acid solution, and the polymerization temperature of 10-60 deg.C is most suitable. Further, it is desirable to use polyethylene or polypropylene film as the synthetic resin film.
