ABSTRACT:
Late transition metal complexes of certain ligands which contain phosphinidine and/or imine groups are useful as components of polymerization catalysts for olefins. Useful metals in the complexes include Ni, Pd, Fe and Co. Oligomers and/or polymers of olefins such as ethylene can be made.
