Abstract
The present disclosure provides catalyst compounds having an amine bridged anilide phenolate ligand. In at least one embodiment, catalysts of the present disclosure provide catalyst activity values of about 90 gP/mmolCat·h−1 or greater and polyolefins, such as polyethylene copolymers, having comonomer content of from about 4 wt % to about 12 wt %, an Mn of about 90,000 g/mol or more, an Mw of 155,000 g/mol or more, and an Mw/Mn of from 1 to 2.5.
