Linked metallocene complexes, catalyst systems, and olefin polymerization processes

摘要

Disclosed are metallocene complexes containing two or more metallocene components where the components may be independently bridged or unbridged. In particular, the invention provides metallocene complexes including a bridged metallocene component linked to an unbridged metallocene component where a ligand structure of the unbridged metallocene component is linked to the bridging group of the bridged metallocene component. The invention provides metallocene complexes including a first unbridged metallocene component linked to second unbridged metallocene component via their ligand structures. The invention also provides metallocene complexes including a bridged metallocene component linked to a second bridged metallocene component via their ligand structures. The invention further provides methods of preparing the linked metallocene complexes described above, catalyst systems including these linked metallocene complexes, polymerization processes utilizing these complexes, and polymers made thereby.
