Abstract
Disclosed herein are compounds and processes useful for the oligomerization and polymerization of olefins. Transition metal catalyst complexes of groups 7 through 10 with tridentate ligands are described, along with a representative polymerization of ethylene using one of the cobalt complexes. The transition metal complexes of the invention may also be attached to a solid support and used in gas phase processes.
