This disclosure is generally directed to polymerization catalysts derived from 1,5-diazabicyclooctanes, catalyst systems utilizing such catalysts, and processes to polymerize alpha olefins therewith.

1,5 diazabicyclooctane ligand systems and methods therewith

The present disclosure provides catalyst compounds represented by Formula (I): where Q is OR, SR, NRR, PRR, or a heterocyclic ring; each Ris independently hydrogen, C-Chydrocarbyl, substituted C-Chydrocarbyl, a heteroatom, or a heteroatom-containing group, or multiple Rare joined together to form a C-Ccyclic, heterocyclic, or polycyclic ring structure, or combination(s) thereof; each Xand Xis independently C-Chydrocarbyl, substituted C-Chydrocarbyl, a heteroatom, or a heteroatom-containing group, or Xand Xjoin together to form a C-Ccyclic, heterocyclic, or polycyclic ring structure; and Y is a hydrocarbyl. The present disclosure also provides catalyst systems including an activator, a support, and a catalyst of the present disclosure. The present disclosure also provides polymerization processes including introducing olefin monomers to a catalyst system. Additionally, the present disclosure provides a polyolefin formed by a catalyst system or method of the present disclosure.

Catalysts for olefin polymerization

The present disclosure relates to amido-benzoquinone transition metal complexes, catalyst systems including amido-benzoquinone transition metal complexes, and polymerization processes to produce polyolefin polymers such as polyethylene-based polymers and polypropylene-based polymers.
