Halogen substituted metallocene compounds are described and comprise one or more monocyclic or polycyclic ligands that are pi-bonded to the metal atom and include at least one halogen substituent directly bonded to an sp

carbon atom at a bondable ring position of the ligand, wherein the or at least one ligand has one or more ring heteroatoms in its cyclic structure. When combined with a suitable activator, these compounds show activity in the polymerization of olefins, such as ethylene and propylene.
本文介绍了卤代金属茂金属化合物,包括一个或多个单环或多环配体,这些配体与金属原子通过π键相连,并且在配体的可键环位置上直接与sp2碳原子结合至少一个卤素取代基,其中至少一个配体在其环状结构中具有一个或多个环异原子。当与适当的活化剂结合时,这些化合物在烯烃聚合中表现出活性,例如乙烯和丙烯。
