SYNTHESIS OF ARYL COUPLED BIS PHENOXIDES AND THEIR USE IN OLEFIN POLYMERIZATION CATALYST SYSTEMS WITH ACTIVATOR-SUPPORTS

Disclosed herein are methods of making bis(phenol) ligand compounds and transition metal bis(phenolate) compounds. The transition metal bis(phenolate) compounds can be used as components in catalyst systems for the polymerization of olefins.

Surprising activity for group 4 polyolefin catalysts [M{(OAr)2py}Cl2(thf)] (M = Zr, Ti) bearing tridentate pyridine-2,6-bis(aryloxide) ligands

Unexpectedly high ethylene polymerisation activity is observed for zirconium(IV) catalysts supported by a rigid tridentate pyridine-bis(phenolate) ligand in conjunction with MAO; a methodology towards analogues with unsymmetric ligands and the significanc
