Abstract

Catalyst compositions useful for the polymerization or oligomerization of olefins are disclosed. Certain of the catalyst compositions comprise metal complexes of mono through tetradentate ligands comprising N-pyrrolyl substituted nitrogen donors bonded to the metal. Also disclosed are processes for the polymerization or oligomerization of olefins using the catalyst compositions.
