    摘要： A process for producing alpha-olefin dimers comprises contacting, at a temperature of 80° C. or more, a feedstock comprising at least one C8+ (linear) alpha-olefin with a catalyst system comprising activator and one or more catalyst compounds represented by the formula: where M is a Group 4 metal; n is 1, 2, or 3; RA is hydrogen or a C1 to C10 alkyl; each of R1, R2, R3, R4, R5, R6, R7, and R8 is independently selected from hydrogen and C1 to C10 alkyl; each X is independently selected from the group consisting of hydrocarbyl radicals having from 1 to 20 carbon atoms, hydrides, amides, alkoxides, sulfides, phosphides, halides, and a combination thereof, (two X's may form a part of a fused ring or a ring system), the contacting being conducted under conditions effective to oligomerize at least part of C8+ alpha-olefin to produce an oligomerized product containing at least 30 wt % of the alpha-olefin dimer and at least 80 mol % of vinylidene unsaturation, where the conversion of the alpha olefin is at least 10 wt %, based upon the weight of the alpha olefin monomer entering the reactor and the weight of dimer produced.

    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.
