The present disclosure provides catalyst compounds having a tridentate ethylene bridged amine bis(phenolate) ligand. Catalysts of the present disclosure preferably provide catalyst activity values of 250 gP/mmolCat/hr or greater and polyolefins, such as polyethylene copolymers, having comonomer content of 8.5 wt % or greater, an Mn of 190,000 g/mol or greater, an Mw of 350,000 g/mol or greater, and a narrow Mw/Mn (such as about 2). Catalysts, catalyst systems, and processes of the present disclosure can provide polymers having a high comonomer content (e.g., 8.5 wt % or greater).
本公开提供具有三齿乙烯桥胺基双(酚酮)配体的催化剂化合物。本公开的催化剂优选提供250 gP/mmolCat/hr或更高的催化活性值,以及共聚物,如聚乙烯共聚物,其共聚物含量为8.5重量%或更高,Mn为190,000 g/mol或更高,Mw为350,000 g/mol或更高,并且具有窄的Mw/Mn(例如约为2)。本公开的催化剂、催化剂系统和工艺可以提供具有高共聚物含量(例如8.5重量%或更高)的聚合物。
