  • Process for preparing isobutene cyclopentadiene-methylcyclopentadiene terpolymers
    Patent number: 5883207
    Abstract: The present invention relates to a process for preparing isobutene-cyclodiene copolymers having a number-average molecular weight of at least 100,000 and an unsaturation of 1.about.30% by mol, characterized in that polymerization is carried out without gelation by reacting 75.about.99.5% by weight of an isobutene and 0.5.about.25% by weight of a cyclodiene or a mixture of cyclodiene as reaction materials, in a polar reaction solvent of 1.about.10 times by weight with respect to the reaction materials, wherein a catalyst solution of 0.02.about.2% by weight in the polar solvent is used in the amount of 0.2.about.2 times by weight with respect to the reaction materials, at a reaction temperature of -100.degree..about.-85.degree. C., thereby obtaining a copolymer, and then removing the residual catalyst activity at a temperature of -100.degree..about.-25.degree. C.
