Abstract

PURPOSE: An organic high polymer is, after exposed to radiation, kept at low temperature and continuously dipped in a solution of reactive monomers kept at higher temperature than that of the polymer to effect the reaction in an atmosphere of inert gas to produce uniform graft polymer suitably used as a diaphragm for electrolysis.
CONSTITUTION: A roll sheet of organic high polymer such as polyethylene is irradiated with 0.1W90 Mrad of electron or gamma rays and set in an unrolling chamber which is kept below 0°C in an atmosphere of inert gas such as nitrogen so that the decrease of radicals formed is prevented. Then, the rolled sheet is unrolled and dipped in a solution of a reactive monomer such as acrylic acid that is kept less than 5ppm in the oxygen content by use of an inert gas, preferably less than 2ppm at 10W60°C to produce the objective graft polymer.
