Metallocene-catalyzed olefin polymerization in the absence of aluminoxane |
摘要 |
The present invention is directed to a method for polymerizing an alpha -olefin characterized by using a catalyst system which is obtained by reacting a halogenated metallocene compound with an organometallic compound, and then bringing the resultant reaction product into contact with a compound which will be a stable anion by reaction with the reaction product of the halogenated metallocene compound and the organometallic compound. When the method of the present invention is carried out, a polyolefin can be obtained by the use of the inexpensive catalyst in a high activity per unit amount of the catalyst.
