    摘要： The present disclosure relates to Lewis base catalysts. Catalysts, catalyst systems, and processes of the present disclosure can provide high temperature ethylene polymerization, propylene polymerization, or copolymerization as the Lewis base catalysts can be stable at high polymerization temperatures and have good activity at the high polymerization temperatures. The stable catalysts with good activity can provide formation of polymers having high melting points, high isotacticity, and controllable molecular weights, and the ability to make an increased amount of polymer in a given reactor, as compared to conventional catalysts. Hence, the present disclosure demonstrates highly active catalysts capable of operating at high reactor temperatures while producing polymers with controlled molecular weights and or robust isotacticity.

    摘要： Disclosed are new classes of pyridyldiamide catalyst components useful in olefin polymerization, an example of which includes: wherein M is a hafnium or zirconium; R1 and R11 are selected from phenyl and substituted phenyl, wherein the substitutions are selected from C1 to C5 hydrocarbyls, preferably C2 to C4 hydrocarbyls, and can reside in any of the ortho, meta, para positions on the phenyl ring; R2′ and R2″ are selected independently from hydrogen and C1 to C6 hydrocarbyls, preferably hydrogen; R10 is a hydrocarbyl bridging group; R3, R4, and R5 are independently selected from hydrogen, hydrocarbyls, and substituted hydrocarbyls; and R6, R7, R8, and R9 are independently selected from hydrogen, hydrocarbyls, and substituted hydrocarbyls; wherein R6 and R7 form an aromatic ring or R7 is hydrogen and R6 is selected from methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, and tert-butyl, preferably methyl.

    摘要： The present disclosure relates to Lewis base catalysts. Catalysts, catalyst systems, and processes of the present disclosure can provide high temperature ethylene polymerization, propylene polymerization, or copolymerization as the Lewis base catalysts (e.g., bis(aryl phenolate) five-membered ring catalysts), can be stable at high polymerization temperatures and have good activity at the high polymerization temperatures. The stable catalysts with good activity can provide formation of polymers having high molecular weights or polymers having low to very molecular weights, and the ability to make an increased amount of polymer in a given reactor, as compared to conventional catalysts. Hence, the present disclosure demonstrates highly active catalysts capable of operating at high reactor temperatures while producing polymers with controlled molecular weights and or robust isotacticity.
