New ligands, compositions, metal-ligand complexes and arrays with pyridylamine ligands are disclosed that catalyze the polymerization of monomers into polymers. Certain of these catalysts with hafnium metal centers have high performance characteristics, including higher comonomer incorporation into ethylene/olefin...http://www.google.fr/patents/US6900321?utm_source=gb-gplus-shareBrevet US6900321 - Substituted pyridyl amine complexes, and catalysts
