<p>A process for preparing oligomer resins from compounds containing carbon-carbon unsaturated double bonds with the aid of a perfluoroalkane-class ion exchange material serving as a catalyst. The process is characterized by allowing compounds containing carbon-carbon unsaturated double bonds, a styrene-class compound such as styrene and alpha -methylstyrene, and a vinyl compound such as alpha -olefin, indene, coumarone, acenaphthylene or the like to polymerize, with the aid of a perfluoroalkane-class ion exchange material serving as a catalyst, preferably from the viewpoint of corrosion, thermal and solvent resistance and the like an ion exchange membrane of which the matrix comprises fluorine-containing resins, and -SO3H as functional group.</p> |
