Abstract
Ligands, compositions, metal-ligand complexes and arrays with substituted bridged bis-biaromatic ligands, and methods of making and using the same, are disclosed that are useful in the catalysis of transformations such as the polymerization of monomers into polymers. The catalysts have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.
