Metallocenes and Methods Thereof |
| abstract |
The present disclosure provides metallocene catalyst compounds including at least one —Si— containing linker, catalyst systems including such compounds, and uses thereof. Catalyst compounds of the present disclosure can be hafnium-containing compounds having one or more cyclopentadiene ligand(s) substituted with one or more silyl neopentyl groups and linked with at least one —Si-containing linker. In another class of embodiments, the present disclosure is directed to polymerization processes to produce polyolefin polymers from catalyst systems including one or more olefin polymerization catalysts, at least one activator, and an optional support. |
