    • PURPOSE: Provided is a method for producing an olefin-cyclic olefin copolymer having by using methylene-bridged metallocene catalyst excellent in copolymerization and polymerization activity. CONSTITUTION: The method comprises the step of polymerizing an ethylene and a cyclic olefin, or an alpha-olefin and a cyclic olefin in the presence of methylene-bridged metallocene catalyst represented by formula 1. In the formula 1, M is a transition metal of group 4, each of R which is the same or different, is hydrogen radical, C1-C20 alkyl radical, alkenyl radical, aryl radical, alkylaryl radical, arylalkyl radical, or hydrocarbyl-substituted metalloid radical of group 14 metals, each of A and A' is independently or simultaneously, hydrogen, radical, C1-C20 alkyl radical, alkenyl radical, aryl radical, alkylaryl radical, arylalkyl radical, or hydrocarbyl-substituted metalloid radical of group 14 metals, and each of Q is independently or simultaneously, halogen radical, alkyl radical, alkenyl radical, aryl radical, alkylaryl radical, arylalkyl radical, or C1-C20 alkylidene radical.
    • 目的:提供通过使用共聚和聚合活性优异的亚甲基桥接金属茂催化剂制备烯烃 - 环烯烃共聚物的方法。 方案:该方法包括在由式1表示的亚甲基桥接的茂金属催化剂存在下聚合乙烯和环烯烃或α-烯烃和环烯烃的步骤。在式1中,M是过渡金属 组4,相同或不同的R各自为第14族金属的氢原子,C 1 -C 20烷基,烯基,芳基,烷基芳基,芳基烷基或烃基取代的准金属,A和 A'独立地或同时地是第14族金属的氢,自由基,C 1 -C 20烷基,烯基,芳基,烷基芳基,芳基烷基或烃基取代的准金属基,Q各自独立地或同时地是卤素 自由基,烷基,烯基,芳基,烷基芳基,芳基烷基或C 1 -C 20亚烷基。
