    • PROBLEM TO BE SOLVED: To provide a method for efficiently producing a cyclic olefin addition polymer.
      SOLUTION: The method for producing the cyclic olefin addition polymer comprises polymerizing the corresponding cyclic olefin monomer using a metallocene complex represented by either general formula (I), (II) or (III). In the general formula (I), (II) and (III), M is a lanthanoid element, scandium or yttrium; Cp
      R is a (substituted) indenyl; Cp
      R' is a (substituted) cyclopentadienyl, indenyl or fluorenyl; R
      a to R
      f are each hydrogen or a 1-3C alkyl; X and X' are each a hydrogen atom, a halogen atom, alkoxide, thiolato, amido, silyl or a 1-20C hydrocarbon group; L is a neutral Lewis base; w is an integer of 0-3; and [B]
      - is a non-coordination anion.
