Abstract:
1. A method of producing cyclic olefin polymers having polar functional groups, the method comprising: preparing a catalyst system for producing the cyclic olefin polymers having polar functional groups; and addition-polymerizing cyclic olefin monomers having polar functional groups in the presence of an organic solvent and the catalyst system mixture, at a temperature of 80-150° C. wherein the catalyst comprising: i) a procatalyst represented by formula (1) containing a group 10 metal and a ligand containing hetero atoms bonded to the metal; ii) a cocatalyst represented by formula (2) including a salt compound which is capable of providing a phosphonium cation and an anion weakly coordinating to the metal of the procatalyst: where X is a hetero atom selected from S, O and N; R R M is a group 10 metal; and p is an integer from 0 to 2, and where each of a, b and c is an integer from 0 to 3, and a+b+c=3; Z is O, S, Si or N; d is 1 when Z is O or S, d is 2 when Z is N, and d is 3 when Z is Si; R each of R [Ani] is an anion capable of weakly coordinating to the metal M of the procatalyst represented by formula (1) and is selected from the group consisting of borate, aluminate, [SbF
