Document Type and Number:

WIPO Patent Application WO/2024/004884

Kind Code:

A1

Abstract:

A method for producing a varnish-like cyclic olefin copolymer composition containing a cyclic olefin copolymer (m) and an organic solvent, wherein the method for producing a varnish-like cyclic olefin copolymer composition is characterized in that the cyclic olefin copolymer (m) contains (A) one or more repeating units derived from an olefin, (B) one or more repeating units derived from a cyclic unconjugated diene, and (C) one or more repeating units derived from a cyclic olefin; the method includes a polymerization step that copolymerizes the olefin, cyclic unconjugated diene, and cyclic olefin in the presence of a catalyst for olefin polymerization containing a transition metal compound (A) and a compound (B); the transition metal compound (A) contains one or more selected from transition metal compounds (A-1) and transition metal compounds (A-2); and the compound (B) contains one or more selected from the group consisting of organic metal compounds (B-1), organic aluminum oxy compounds (B-2), and compounds (B-3) that react with the transition metal compound (A) to form an ion pair.
