    摘要： Disclosed are olefin polymerization methods comprising the use of the following compounds: wherein M is a metal atom, R1-R8 are univalent radicals, X1 and X2 are univalent ligands, X3 is a divalent ligand, and (RnY—T) is an optional donor or non-donor group. The relatively stable and simply synthesized pre-catalyst is activated by a co-catalyst under mild reaction conditions, producing exceptionally reactive polymerization of a wide variety of alpha-olefin monomers, and forming a variety of poly(alpha-olefin) products, having high molecular weight and low molecular weight distribution (PDIs close to 1). Living polymerization is performed at or above room temperature, along with achieving block co-polymerization of alpha-olefin monomers at room temperature, and producing polymers and oligomers having a wide range of molecular weights. The catalyst formed during reaction remains ‘alive’ for as long as 31 hours, for producing a polymer with a molecular weight as high as 450,000 grams/mole.
