ABSTRACT:
The present invention provides a non-metallocene catalyst comprising a complex having one or more ligands coordinated a transition metal. The catalyst contains substituents bonded to the transition metal through a heteroatom such as oxygen or sulfur. Furthermore, the complex includes a Group 3 to 10 transition or lanthanide metal and one or more anionic or neutral ligands in an amount that satisfies the valency of the metal such that the complex has a net zero charge. The present invention also discloses a method for preparing the catalyst and polymerizing olefins utilizing the catalyst of the present invention.
