1. sulfurized elastic composition, it comprises by C 4-C 8Isoolefine derived units, C 4-C 14Polynary alkene derived units and the halogenated terpolymer that the ring-alkylated styrenes derived units is formed, wherein the isoolefine derived units that exists in this halogenated terpolymer is the 70-99.5wt% of terpolymer weight, the 0.2-30wt% that the polynary alkene derived units that exists is a terpolymer weight, what exist is the 0.5-30wt% of terpolymer weight to the ring-alkylated styrenes derived units, and the content of halogen of this halogenated terpolymer is the 0.05-10wt% of terpolymer weight;

  • And wherein each component content sum is 100wt% in this halogenated terpolymer, and the number-average molecular weight of this terpolymer is 80,000-1,000,000, said composition contain vulcanize under the sulfur vulcanization system and vulcanising composition 100 ℃

    of adhesion values to SBR greater than 70N/mm.
