Method for producing cyclic olefin copolymer |
| abstract |
There is provided a process for the production of a cycloolefin copolymer which comprises copolymerizing an alpha -olefin having 2 or more carbon atoms and a specific cycloolefin in the presence of a specific metallocene type catalyst in a solvent mixture of a hydrocarbon solvent having a solubility parameter (value of delta ) of 7.7 Ä(cal/cm<3>)<1/2>Ü or more and a hydrocarbon solvent having a solubility parameter (value of delta ) of 7.5 Ä(cal/cm<3>)<1/2>Ü or less as a polymerization solvent. A cycloolefin copolymer having a high molecular weight can be produced in a high concentration by this process at a high yield. |
