Abstract
Processes for the polymerization of olefins in which late transition metal complexes, such as nickel, iron, cobalt and palladium complexes, are used as a polymerization catalyst have improved polymer productivity when oxidizing agents are present during at least a portion of the polymerization. The polymers produced are useful as elastomers, for packaging films, and molding resins.
