본 발명은 전이 금속 화합물 또는 란탄계 금속 화합물, 알킬화제 및 무기 할라이드 알코올레이트를 포함하는 중합 촉매계를 사용하여 비환식 공액 디엔 및 환식 공액 디엔의 공중합체를 제조하는 방법, 및 이를 포함하는 고무 조성물 및 타이어에 관한 것이다. 공중합체는 90% 이상의 비환식 공액 디엔 단량체를 함유하고, 수평균 분자량이 40,000 내지 300,000이고, 시스-결합 함량이 92% 이상이다.

    A process for preparing a copolymer of an acyclic conjugated diene and a cyclic conjugated diene using a polymerization catalyst system comprising a transition metal compound or a lanthanide metal compound, an alkylating agent, and an inorganic halide alcoholate, and rubber compositions and tires comprising the same. The copolymer contains at least 90% acyclic conjugated diene monomer, has a number average molecular weight of between 40,000 and 300,000, and has a cis-bond content of at least 92%.
