Method for preparing olefin-cyclic olefin copolymer using methylene bridged metallocene catalyst |
| abstract |
The present invention relates to a method for preparing a copolymer of an olefin-cyclic olefin using a metallocene catalyst, wherein an ethylene and a cyclic olefin, or an alpha olefin and a cyclic olefin are two carbon atoms between two cyclopentadienyl groups. The methylene bridge, which is bridged to and has a large angle between the cyclopentadienyl groups and has a substituent only at the alpha position relative to the bridge position of the cyclopentadienyl group, increases the activity of the catalyst by the electronic effect and has the least steric hindrance. It provides a method for producing an olefin-cyclic olefin copolymer comprising the step of polymerizing under a metallocene catalyst. |
