2. Description of the Related Art Many reports have already been made on a method for producing an olefin polymer using a metallocene complex. For example, in JP-A-58-19309,
A method for producing an olefin polymer using a metallocene complex and an aluminoxane has been reported. When olefin polymerization is carried out with a catalyst using this bis (cyclopentadienyl) zirconium dichloride and methylaluminoxane, there is a problem that the molecular weight of the olefin polymer obtained is low. In order to improve this problem, WO87 /
In 02370, it is reported to use a reaction product of an organic compound having at least two hydroxyl groups and a transition metal compound. However, in the report 2,
Even in a system using 2'-thiobis (6-tert-butyl-4-methylphenoxy) titanium dichloride and methylaluminoxane, 2,2'-thiobis (6-tert-butyl) described in JP-A-5-230133. Even in a system using 4-methylphenoxy) titanium dichloride, triisobutylaluminum and triphenylmethanetetrakis (pentafluorophenyl) boron, although the molecular weight is improved, its activity is low from an industrial viewpoint. there were. Further, known metallocene complexes such as ethylenebis (indenyl) zirconium dichloride, isopropylidene (cyclopentadienyl) (fluorenyl) zirconium dichloride, dimethylsilyl (tert-butylamide) (tetramethylcyclopentadienyl) titanium dichloride, etc. Since it is soluble in an aromatic hydrocarbon solvent but insoluble in a saturated hydrocarbon solvent, a polymerization catalyst containing such a complex should be produced using a saturated hydrocarbon solvent to produce a polymer. I couldn't.

[0003]

In view of such a situation, the present invention is a complex which is highly active at a reaction temperature and soluble in a saturated hydrocarbon solvent in an industrial process of olefin polymerization which is important from an industrial viewpoint. The present invention provides a highly active catalyst for olefin polymerization containing the complex, and a method for producing an olefin polymer using the catalyst.
