Patent ID: 7977268

Claim:
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: R 1 , R 2 and R 3 are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl, or an inert functional group; R 4 and R 5 are each independently hydrogen, hydrocarbyl, an inert functional group or substituted hydrocarbyl; and R 6 and R 7 are aryl or substituted aryl; and provided that said first active polymerization catalyst produces an oligomer of the formula R 60 CH═CH 2 from said ethylene, wherein R 60 is n-alkyl; (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: one or both of said first olefin and said second olefin is ethylene; and a branched polyolefin is a product of said polymerization process.
