Abstract:
1. A process for the polymerization of olefins, comprising, contacting under polymerizing conditions: (a) a first active polymerization catalyst for said olefins which is a Fe or Co complex of a ligand of the formula: wherein: (b) a second active polymerization catalyst for said olefins which contains one or more transition metals; (c) a least one first olefin capable of being polymerized by said first active polymerization catalyst; and (d) at least one second olefin capable of being polymerized by said second active polymerization catalyst and said second active polymerization catalyst being capable of copolymerizing said second olefin and said oligomer; and provided that: a branched polyolefin is a product of said polymerization process.
