| titleOfInvention | Ring-opening metathesis polymerization catalyst and method for producing cyclic olefin polymer using the same |
| abstract | The present invention provides a novel ring-opening metathesis polymerization catalyst that can be easily prepared from readily available raw materials, and a method for producing a cyclic olefin polymer using the catalyst. The ring-opening metathesis polymerization catalyst of the present invention is a niobium carbene complex containing low-valence niobium having a valence of 4 or less. This catalyst may be a niobium carbene complex having an alkoxy group as a ligand. Further, this catalyst has the following formula (1): NbX 1 m (1) (Wherein X 1 represents an alkoxy group or a halogen atom, m represents 3 or 5, m X 1 may be the same or different), zinc and carbene It may be prepared by reacting with a forming compound. [Selection figure] None |
