Disclosed are novel bridged bi-aromatic phenol ligands and transition metal catalyst compounds derived therefrom. Also disclosed are methods of making the ligands and transition metal compounds, and polymerization processes utilizing the transition metal compounds for the production of olefin polymers.
New methods for preparing bridged bi-aromatic ligands are disclosed. The methods employ aryl coupling of unprotected phenols. The ligands may be used to prepare transition metal compounds useful as catalysts in olefin polymerization.
