| abstract | (57) [Summary] [Purpose] Production for producing a polymer that exhibits good fluidity and low birefringence and does not generate silver streaks or gels during injection molding of hydrogenated ring-opening polymers. To provide a method. A method for producing a polymer, which comprises a ring-opening polymerization step of metathesis ring-opening polymerization of a specific monomer represented by the following chemical formula 1, wherein the specific monomer is finally opened in the ring-opening polymerization step. 1 to 30% by weight of the amount used for the ring polymerization reaction is dissolved in a solvent together with the metathesis catalyst and the molecular weight modifier, and then the ring opening polymerization reaction is started to finally perform the ring opening polymerization of the specific monomer. 99 to 70% by weight of the amount supplied to the reaction Is added to the reaction system continuously or intermittently to advance the ring-opening polymerization reaction. (A in chemical formula 1 And B are hydrogen atoms or hydrocarbon groups having 1 to 10 carbon atoms, X and Y are hydrogen atoms, halogen atoms or monovalent organic groups, and m is 0 or 1. ) [Chemical 1] |
