The present invention relates to rubber-like terpolymers consisting of isoolefins, conjugated diolefins and other mono- or polyunsaturated organic compounds (with a molecular weight M w from 50,000 to 2,000,000 g / mol) and a process for the preparation of the new terpolymers in the presence of an initiator system based on vanadium tetrachloride hydrocarbon solutions. These terpolymers are used for the production of rubber vulcanizates, in particular tires. |
