Abstract:
1. A method of producing a cyclic olefin polymer having a polar functional group, comprising the step of: bringing a catalyst mixture into contact with a monomer solution containing cyclic olefin monomers having a polar functional group, wherein the catalyst mixture includes a precatalyst containing metal of Group 10 represented by Formula 1, an organophosphorus ligand represented by Formula 2, and a cocatalyst that is a salt compound slightly coordinated with the metal of Group 10 represented by Formula 3 and providing an anion: wherein Xs are each independently a hetero atom selected from S, O, and N, R R M is metal of Group 10, and p is 0 to 2, wherein a, b, and c are each an integer in the range of 1 to 3, Z, Z′, and Z″ are each independently oxygen, sulfur, silicon, or nitrogen, with a proviso that Z, Z′, and Z″ are not the same atom, R wherein [Cat] is a cation and any one selected from the group consisting of hydrogen, cations of metal of Group 1, metal of Group 2, or transition metal, and an organic unit containing the cations, and [Ani] is an anion that is slightly coordinated with metal M of Formula 1 and any one selected from the group consisting of borate, aluminate, [SbF
