Abstract

PURPOSE: To manufacture efficiently excellent permeable membrane having resistance characteristics, by the graft copolymerization of vinyl monomer with a thermoplastic film.
CONSTITUTION: In manufacture of a permeable membrane, especially a permeable membrane used for the separator of a cell, a thermoplastic film is irradiated with electron beam or radiant ray such as γ-ray to form hydroperoxide or peroxide. Then the plastic film is brought into contact with a mixed liq. of a vinyl monomer capable of imparting electroconductivity with vinyl monomer previously denaturated with reducing metal, to make graft copolymer of both the monomers, thereby manufacturing a permeable membrane. Hereby a permeable membrane having excellent function is manufactured at a good, industrial production efficiency while preventing the formation of homopolymer.
