Catalyst for olefin polymer production and process for olefin polymer production employing the catalyst

摘要

A novel catalyst for olefin polymerization is provided which comprises ÄAÜ a metallocene compound containing a transition metal selected from Groups 3, 4, 5, and 6 of Periodic Table, ÄBÜ a reaction product of topotactic reduction by electron transfer, and ÄCÜ an organoaluminum compound. The catalyst may contain additionally ÄDÜ an organoalkaline earth metal compound or an organozinc compound. This catalyst has high catalytic activity for olefin polymerization without employing an expensive catalyst component.
