Patent ID: 7109277

Claim:
A process to produce a catalyst composition comprising: contacting a catalyst precursor with at least one organometal compound and at least one organoaluminum compound; wherein the catalyst precursor comprises at least one treated solid oxide compound and at least one alpha olefin; wherein the at least one treated solid oxide comprises a contact product of at least one solid oxide compound, at least one electron-withdrawing anion source compound, and optionally, at least one metal salt compound; wherein the organometal compound has the following general formula: (X 1 )(X 2 )(X 3 )(X 4 ) M 1 wherein M 1 is selected from titanium, zirconium, or hafnium; wherein (X 1 ) and (X 2 ) are independently selected from cyclopentadienyls, indenyls, fluorenyls, substituted cyclopentadienyls, substituted indenyls, or substituted fluorenyls; wherein substituents on the substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls of (X 1 ) and (X 2 ) are selected from aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, silyl groups, alkyl halide groups, halides, organometallic groups, phosphorus groups, nitrogen groups, silicon, phosphorus, boron, germanium, or hydrogen; wherein at least one substituent on (X 1 ) and (X 2 ) is a bridging group which connects (X 1 ) and (X 2 ) ; wherein (X 3 ) and (X 4 ) are independently selected from halides, aliphatic groups, substituted aliphatic groups, cyclic groups, substituted cyclic groups, combinations of aliphatic groups and cyclic groups, combinations of substituted aliphatic groups and cyclic groups, combinations of aliphatic groups and substituted cyclic groups, combinations of substituted aliphatic groups and substituted cyclic groups, amido groups, substituted amido groups, phosphido groups, substituted phosphido groups, alkyloxide groups, substituted alkyloxide groups, aryloxide groups, substituted aryloxide groups, organometallic groups, or substituted organometallic groups; and wherein the organoaluminum compound has the following general formula: Al(X 5 ) n (X 6 ) 3-n wherein (X 5 ) is a hydrocarbyl having from 1–20 carbon atoms; wherein (X 6 ) is a halide, hydride, or alkoxide; and wherein “n” is a number from 1 to 3 inclusive.
