Patent ID: 7906451

Claim:
A polymerization catalyst component, comprising: (a) a first active polymerization catalyst for ethylene 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; (b) a second active polymerization catalyst for one or more olefins which contains one or more transition metals and wherein said second polymerization catalyst copolymerizes ethylene and an oligomer of the formula R 60 CH═CH 2 ; and (c) a catalyst support; provided that said first polymerization catalyst produces said oligomer of the formula R 60 CH═CH 2 from ethylene, wherein R 60 is n-alkyl containing from 1 to 20 carbon atoms, and provided that said second polymerization catalyst produces a polymer with an average degree of polymerization of at least about 50.
