| titleOfInvention | Norbornene monomer ring-opening polymerization catalyst system, and ring-opening polymer and method for producing ring-opening polymer hydride |
| abstract | Provided is a ring-opening polymerization catalyst system capable of obtaining a norbornene-based ring-opening polymer excellent in filtration performance and a hydride thereof at a relatively low cost by improving a ring-opening polymerization method of a norbornene-based monomer. To do. A ring-opening polymerization catalyst system of a norbornene monomer comprising a combination of (a) a tungsten compound, (b) an organoaluminum compound, (c) a secondary alcohol, and (d) a tertiary alcohol. The molar ratio (c / b) of the secondary alcohol to the organoaluminum compound is 0.90 to 1.15, and the molar ratio (d / b) of the tertiary alcohol to the organoaluminum compound is A ring-opening polymerization catalyst system of a norbornene-based monomer within a range of 0.01 to 0.11. [Selection figure] None |
