CA 2483192
New ligands, compositions, metal-ligand complexes and arrays with bridged bis- aromatic ligands are disclosed that catalyze the polymerization of monomers into polymers. These catalysts with metal centers 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.
L'invention concerne des ligands, des compositions, des complexes métal-ligand et des réseaux de ligands biaromatiques pontés catalysant la polymérisation de monomères en polymères. Ces catalyseurs à centre métallique possèdent des caractéristiques élevées de performance, y comprise une incorporation plus importante de comonomère dans des copolymères éthylène/oléfine, où ces oléfines sont, par exemple, du 1-octène, du propylène ou du styrène. Ces catalyseurs permettent aussi de polymériser du propylène en polypropylène isotactique.
