| titleOfInvention | Methods to produce polyolefins with catalytic systems |
| abstract | A method of producing a polyolefin, comprising: contacting one or more olefins with a catalyst system in a polymerization reactor under conditions sufficient to produce a polyolefin, wherein the catalyst system comprises a first metallocene catalyst compound comprising: a first transition metal atom; two cyclopentadienyl ligands attached to the first transition metal atom, and two leaving groups attached to the first transition metal atom, wherein at least one leaving group is selected from the group consisting of a halo-phenoxy and a halo-alkoxy; wherein the first metallocene catalyst compound is selected from (tetramethylcyclopentadienyl) (n-propylcyclopentadienyl) zirconium bis (pentafluorophenoxide); bis (n-butylcyclopentadienyl) zirconium bis (pentafluorophenoxide); bis (n-propylcyclopentadienyl) hafnium bis (pentafluorophenoxide); bis (3-n-butyl-1-methylcyclopentadienyl) zirconium bis (pentafluorophenoxide); bis (pentafluorophenoxide) of rac-Me2Si (tetrahydroindenyl) 2Zr; or any combination thereof; and wherein the first metallocene catalyst compound has a catalyst productivity that is at least 20% higher than a comparative metallocene catalyst compound used to produce the same polyolefin, wherein the comparative metallocene catalyst compound is the same as the first metallocene catalytic compound but does not have a leaving group which is a halo-phenoxy or a halo-alkoxy and instead has methyl leaving groups. |
