Mixed polymerization catalyst component for polymerizing olefins

1. 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.

2. The polymerization catalyst component as recited in claim 1 wherein said second active polymerization catalyst is a Ziegler-Natta or a metallocene polymerization catalyst.

3. The polymerization catalyst component as recited in claim 1 wherein said support is alumina, silica or a polyolefin.

4. The polymerization catalyst component as recited in claim 1 wherein a polymerization catalyst activator for one or both of (a) and (b) is present and is an alkylaluminum compound.

5. The polymerization catalyst component as recited in claim 1 wherein said second active polymerization catalyst is a transition metal complex of a bis(carboximidamidatonate).
