Metallocene and half sandwich dual catalyst systems for producing broad molecular weight distribution polymers

摘要

Disclosed herein are polymerization processes for the production of olefin polymers. These polymerization processes can use a dual catalyst system containing a zirconium or hafnium based metallocene compound and a titanium based half-metallocene compound containing an indenyl group.

主权项

1. An olefin polymerization process, the process comprising:
contacting a catalyst composition with an olefin monomer and optionally an olefin comonomer under polymerization conditions to produce an olefin polymer having a Mw in a range from about 100,000 to about 500,000 g/mol, wherein the catalyst composition comprises catalyst component I, catalyst component II, an activator, and an optional co-catalyst, wherein: catalyst component I comprises a zirconium or hafnium based metallocene compound; and catalyst component II comprises a titanium based half-metallocene compound containing an indenyl group.
