A catalyst system capable of producing a cyclic olefin polymer having a polar functional group and a high molecular weight with a high yield in which a catalyst is not deactivated due to polar functional groups of monomers, and a method of producing polymers using the same are provided. The catalyst system for polymerization of olefin according to the present invention has good thermal and chemical stability, and thus, in the method of preparing polyolefin using the catalyst system, the deactivation of a catalyst due to a polar functional group of the monomer can be prevented, and thus a high yield of the cyclic olefin polymer with a high molecular weight can be obtained when a ratio of the catalyst to the monomer is 1:5000, and the removal of a catalyst residue is not required.
提供了一种催化剂体系,能够产生具有极性功能基和高分子量的环状烯烃聚合物,并具有高产率,其中催化剂不会因单体的极性功能基而失活,以及使用相同的聚合物生产方法。根据本发明的烯烃聚合催化剂体系具有良好的热稳定性和
