Abstract:

A self-supported hybrid olefin polymerization catalyst comprising a Ziegler-Natta component and a metallocene component whereby the metallocene component is affixed to the Ziegler-Natta component is disclosed. In the hybrid catalyst, the Ziegler-Natta component includes a solid complex of magnesium, transition metal, and alkoxide moieties where the transition metal is selected from one or more metals having an oxidation state of +3, +4, +5, and mixtures thereof. A method of making the hybrid catalyst and a method of polymerizing olefins using the hybrid catalyst also are disclosed. The hybrid catalyst is capable of producing polyolefins having a broad molecular weight, or bimodal distribution in high yield.
