Highly active titanium-based olefin polymerization catalysts supported by bidentate phenoxyamide ligands.

Phenoxyamide complexes of Ti-containing 2,6-X 2 C 6 H 3 (X = Cl, Br) substituents, when activated by methyl aluminoxane, afford catalysts with very high activities for the polymerization of ethylene and with good incorporation of 1-hexene.
