ABSTRACT:
New compositions, titanium-ligand complexes and arrays with pyridyl-amine ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with titanium metal centers have high performance characteristics, including high styrene incorporation into ethylene/styrene copolymers.
