    摘要： A novel process for the production of a separator for use in a cell to prevent the short-circuiting of positive active material and negative active material comprises irradiating a polyolefin film 150 .mu.m or less thick with ionizing radiation at a dose rate of 5.times.10.sup.4 -10.sup.7 rads/sec. to give a total dose of 1 Mrad or more, contacting the irradiated film with an aqueous solution of a terminally unsaturated monomer such as acrylic acid, methacrylic acid and the like at a temperature of 10.degree. C.-60.degree. C. to thereby cause grafting of the monomer onto the polyolefin film before the grafted polymer film is treated with an aqueous alkaline solution to finally obtain the separator for use in a cell, which is substantially improved in that it shows low electrical resistance and is excellent both in its acid resistance and mechanical strength.

    摘要： A battery separator composed of a composite sheet of film to which a monomer having a hydrophilic or electrolytic group is grafted is disclosed. Said film consists of a first polymeric layer containing a substance capable of catching a metal ion dissolved from a positive or negative active material and a second polymeric layer integrally bonded to either one or both sides of the first polymeric layer and which contains no such substance or contains it in a smaller amount that that contained in said first polymeric layer. Also disclosed is a method of producing a battery separator by irradiating such composite sheet of film with ionizing radiation and immersing the irradiated film in a solution of a monomer containing a hydrophilic or electrolytic group or bringing it into contact with the monomer solution to thereby graft the monomer to the film.

    摘要： A novel graft copolymer and a process for the production thereof is disclosed, said graft copolymer comprising a backbone chain of a fluoropolymer and side chains grafted thereon consisting essentially of at least a member selected from the group consisting of acyloxystyrene, diacyloxystyrene, hydroxystyrene and dihydroxystyrene or consisting essentially of a mixture of at least a member selected from the group mentioned above and a polyene compound. The grafting is conveniently carried out with the aid of an ionizing radiation. The novel graft copolymer has a wide variety of uses due to its improved characteristic properties such as, for example, improved adhesion properties, improved dyeing properties, improved reactivity to other compounds and the like.
