    摘要： Liquid poly-alpha-olefins having a KV100 of 2 to 6000 cSt, 20 weight percent dimer or less and a viscosity index of 60 or more are obtained by contacting in a reaction zone, in the presence of from 0 to 60 psi hydrogen, C3 to C20 alpha-olefin monomers with a non-coordinating anion activator, a single bridged meso-metallocene transition metal compound having less than about 35 wt % racemic isomer, and a co-activator. The molar ratio of activator to meso-metallocene is from 10:1 to 0.1:1, and the alpha-olefin monomers in the feed components are present in at least 20 wt % or more based upon the weight of the meso-metallocene, non-coordinating anion activator, co-activator, monomers, and solvent or diluent. The productivity of the process is at least 50,000 g of total product per gram of transition metal compound and no more than 5% monomer is converted from olefin to alkane.

    摘要： The present invention relates to processes to produce liquid poly-alpha-olefins comprising: a) contacting in a reaction zone, in the presence of from 0 to 60 psi hydrogen, one or more C3 to C20 alpha-olefin monomers with a non-coordinating anion activator, a single bridged meso-metallocene transition metal compound having less than about 35 wt % racemic isomer, and a co-activator selected from the group consisting of alkyl aluminum compounds and alkyl alumoxanes, provided that when the alkyl alumoxane is present it is present in a molar ratio of less than 0.1:1 of alkylalumoxane to meso-metallocene, and provided that when the alkyl aluminum compound is present it is present at a molar ratio of alkyl aluminum to meso-metallocene of from 2:1 to 10,000 to 1, where the molar ratio of activator to meso-metallocene is from 10:1 to 0.1:1, and provided that ethylene is not present at more than 30 volume % of the monomers entering the reaction zone, and provided that the alpha-olefin monomers in the feed components are present in at least 20 wt % or more based upon the weight of the meso-metallocene, non-coordinating anion activator, co-activator, monomers, and solvent or diluent, and where: i) the productivity of the process is at least 50,000 g of total product per gram of transition metal compound (where the total product is defined to be the total amount of product exiting the reactor, minus unreacted monomers and solvents); and ii) no more than 5% monomer is converted from olefin to alkane; and b) obtaining a liquid polyalphaolefin product having a pour point of less than 25° C., a KV100 of 2 to 6000 cSt, 20 weight percent dimer or less and a viscosity index of 60 or more.
