| 摘要 |
A process for producing an ion exchange membrane comprising impregnating a base material with a polymerizable monomer material and polymerizing the monomer material, if necessary, followed by a reaction for introducing ion exchange groups, wherein said base material is made of an olefin polymer and/or a fluorinated olefin polymer, said polymerizable monomer material is a mixture comprising styrene, chloromethylstyrene and divinylbenzene as three essential components, and the polymerizable monomer material impregnated in the base material is firstly partially polymerized by irradiation of ionizing radiation, and subsequently completely polymerized by heating in the presence of a polymerization initiator. |
