Abstract
The present invention relates to catalytic complexes for the polymerization and copolymerization of olefins comprising the reaction product of a halogenated derivative of a transition metal with a chelate organic oxygenated bivalent metal compound substantially free of hydroxyl groups; to the catalyst compositions formed by activating such complexes with an organometallic compound; and to the processes of forming such catalytic complexes and polymerizing and copolymerizing olefins utilizing such catalyst compositions.
