Ligands, compositions, metal-ligand complexes and arrays with substituted bridged bis-biaromatic ligands and method 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 catalyts have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for exmaple, 1-octene, propylene or styrene. The catalysts also polymerize propylene into isotactic polypropylene.
揭示了具有替代桥联双取代双芳香配体的配体、组合物、金属配体复合物和阵列,以及制备和使用这些材料的方法,这些材料在催化转化中非常有用,例如将单体聚合成聚合物。这些催化剂具有高性能特征,包括将较高量的共聚单体并入乙烯/烯烃共聚物中,其中这些烯烃例如为1-辛烯、丙烯或苯乙烯。该催化剂还将丙烯聚合成等正丙烯。
