BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a catalyst for olefin polymer production comprising a metallocene compound, a reaction product of topotactic reduction by electron transfer, and an organoaluminum compound, and a process for producing an olefin polymer employing the catalyst.

The present invention relates also to a catalyst for olefin polymer production comprising a metallocene compound, a product of a topotactic reduction reaction by electron transfer, an organoaluminum compound, an organoalkaline earth metal compound or an organozinc compound, and a process for producing an olefin polymer employing the catalyst.

2. Description of the Related Art

A catalyst composed of a metallocene compound and an organoaluminum compound, and another catalyst composed of a metallocene compound, an organoaluminum compound, and an organomagnesium compound are disclosed as the catalyst for producing an olefin polymer (JP-A-3-197513, and JP-A-3-290408). However, these catalysts are not satisfactory in the catalyst activity.

Active catalysts for olefin polymer production are disclosed which are composed of a metallocene compound and a methylaluminoxane (JP-A-58-19309, and JP-A-60-35007). These catalyst employs a large amount of expensive aluminoxane to produce a polymer having industrially useful properties, which causes problems of high catalyst cost and residual aluminum.

Highly active olefin polymerization catalysts not containing the methylaluminoxane are disclosed which comprises a metallocene compound, a boron compound, and an organoaluminum compound (Kohyo 1-501950, and Kohyo 1-502036). However, the boron compound for this catalyst is disadvantageously complicated and expensive.

SUMMARY OF THE INVENTION

The present invention intends to solve the above technical problems, and to provide a catalyst for olefin polymer production with high catalyst activity without using an expensive catalyst component. The present invention also provides a process for producing an olefin polymer with the catalyst.

The olefin polymerization catalyst of the present invention comprises [A] a metallocene compound containing a transition metal selected from Groups 3, 4, 5, and 6 of Periodic Table, [B] a reaction product of topotactic reduction with electron transfer, and [C] an organoaluminum compound.

The olefin polymerization catalyst of another embodiment of the present invention comprises [A] a metallocene compound containing a transition metal selected from Groups 3, 4, 5, and 6 of Periodic Table, [B] a reaction product of topotactic reduction by electron transfer, [C] an organoaluminum compound, and [D] an organoalkaline earth metal compound or an organozinc compound.

The process for producing an olefin polymer of the present invention uses the above catalyst.
