    摘要： Provided is a method of preparing a cyclic olefin polymer by addition polymerization of a cyclic olefin monomer, the method including contacting a metal catalyst complex represented by Formula 1 below with a cyclic olefin monomer. [M(L1)x(Ll2)y(L3)z]a[Ani]b wherein M is a Group X metal; [M(Li)χ(L'2)y(L3)z] is a cationic complex; Li is an anionic hydrocarbyl-containing ligand; U2 is a neutral ligand; L3 is an N-heterocyclic carbene ligand; [Ani] is an anion capable of weakly coordinating with the metal M; x is 1 or 2; y is 0 to 4; z is 1 or 2;2≤x+y+z≤6; a and b are respectively the number of cations and the number of anions capable of weakly coordinating with the metal M and are each a number of 1-10 which is used to satisfy the net charge balance of the metal catalyst complex, and wherein for each of L1, L2, and L3, when a plurality of ligands are present in a molecule of the metal catalyst complex, the ligands may be the same or different. According to the method of the present invention, a high molecular weight cyclic olefin addition polymer can be produced in a high yield even when using a polar functional group-containing cyclic olefin monomer. A polymer produced using the method shows good thermal stability.
