Self-supported hybrid catalysts for the production of polyolefins |
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 groupe 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. |
