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.
Claims29
A catalyst compound represented by Formula 4):
- wherein:
- M is a group 4 metal;
- R1 is an aromatic group or substituted aromatic group;
- each of R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, and R14 is independently hydrogen, C1-C40 hydrocarbyl, C1-C40 substituted hydrocarbyl, a heteroatom or a heteroatom-containing group, or two or more of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, and R14 are joined together to form a C4-C62 cyclic or polycyclic ring structure;
- each X is independently C1-C20 hydrocarbyl, C1-C20 substituted hydrocarbyl, a heteroatom or a heteroatom-containing group, or two or more Xs join together to form a C4-C62 cyclic or polycyclic ring structure.
