【発明の名称】混合金属アルコキサイドおよびポリオレフィン製造用シクロアルカジエニル触媒
Document Type and Number:
Japanese Patent JP2003518529
Kind Code:
A
Abstract:
A solid self-supported cycloalkadienyl catalyst component is disclosed that includes: (i) a mixed metal alkoxide complex which is the reaction product of a magnesium alkoxide or aryloxide and at least one group IVB metal-containing alkoxide or aryloxide; and (ii) Cp, where Cp is a cyclic or polycyclic hydrocarbon having from 3-30 carbon atoms. A self-supported hybrid catalyst also is disclosed which contains the above components (i) and (ii), as well as (iii) a Ziegler-Natta catalyst species. A method of making the self-supported cycloalkadienyl catalyst and the self-supported hybrid catalyst and a method of polymerizing olefins using the catalysts also are disclosed. The catalysts are capable of producing polyolefins in high yield having a broad molecular weight distribution, or a bimodal distribution.
