Hybrid ziegler-natta and cycloalkadienyl catalysts for the production of polyolefins |
摘要 |
A solid self-supported hybrid catalyst is disclosed which contains (i) a Ziegler-Natta catalyst component including at least one group IVB metal-containing alkoxide or aryloxide; and (ii) Cp, where Cp is a cycloalkadienyl hydrocarbon having from 3-30 carbon atoms. A method of making 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 molecular weight distribution.
