The present invention provides: a metathesis polymerization catalyst liquid evaluation method that assesses whether a metathesis polymerization catalyst liquid, which is obtained by adding a metathesis polymerization catalyst to a solvent and which is to be used in a bulk polymerization reaction of a cycloolefin monomer, can be used in the bulk polymerization reaction, the evaluation method being characterized by measuring the specific gravity of a solution portion of the metathesis polymerization catalyst liquid and, on the basis of the obtained specific gravity value, assessing whether the metathesis polymerization catalyst liquid can be used in the bulk polymerization reaction of the cycloolefin monomer; and a cycloolefin polymer production method that uses a metathesis polymerization catalyst liquid that has been assessed by this evaluation method as being able to be used in the bulk polymerization reaction. According to the present invention, even in cases where a cycloolefin polymer is produced on an industrial scale, it is possible to efficiently assess whether a metathesis polymerization catalyst liquid can be used in a bulk polymerization reaction of a cycloolefin monomer and it is possible to produce a cycloolefin polymer having uniform quality at a high polymerization conversion rate. |
