New ligands and compositions 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.
新的配体和含有桥联双芳香配体的组合物被披露,这些配体催化单体聚合成聚合物。这些带有金属中心的催化剂具有高性能特征,包括更高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。这些催化剂还将丙烯聚合成同构聚丙烯。
