Abstract: Method for producing graft polymers from a cyclic olefin as graft monomer and from a polymer containing carbon-carbon double bonds as the grafting base wherein the grafting reaction is effected by a catalyst comprising A. A COMPOUND OF A METAL OF Group VB or VIB of the Mendeleev Periodic System, and B. AN ORGANIC COMPOUND OF A METAL OF Group IA to IIIA of the Mendeleev Periodic System. AND GRAFT POLYMERS OBTAINED IN THIS PROCESS.
