Abstract:
A process to produce a catalyst composition, said process comprising contacting an organometal compound, an organoaluminum compound, and a treated solid oxide compound to produce a catalyst composition substantially free of aluminoxane compounds and fluoro organic borate compounds,wherein said organometal compound has the following general formula: (X1)(X2)(X3)(X4)M1 wherein M1 is selected from the group consisting of titanium, zirconium, and hafnium; wherein (X1) is independently selected from the group consisting of cyclopentadienyls, indenyls, fluorenyls, substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls; wherein said substituents, on said substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls of (X1), are selected from the group consisting of aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, silyl groups, haloalkyl groups, halides, hydrogen, phosphorus groups, nitrogen groups, and organometallic groups selected from the group consisting of substituted silyl derivatives, substituted tin groups, substituted germanium groups, and substituted boron groups; wherein at least one substituent on (X1) can be a bridging group which connects (X1) and (X2); wherein (X3) and (X4) are independently selected from the group consisting of 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, and substituted organometallic groups; wherein (X2) is selected from the group consisting of cyclopentadienyls, indenyls, fluorenyls, substituted cyclopentadienyls, substituted indenyls, substituted fluorenyls, 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, and substituted organometallic groups; wherein substituents on (X2) are selected from the group consisting of aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, silyl groups, haloalkyl groups, halides, hydrogen, phosphorus groups, nitrogen groups, and organometallic groups selected from the group consisting of substituted silyl derivatives, substituted tin groups, substituted germanium groups, and substituted boron groups; wherein at least one substitutent on (X2) can be a bridging group which connects (X1) and (X2); wherein said organoaluminum compound has the general formula: Al(X5)n(X6)3âˆ’n wherein (X5) is a hydrocarbyl having from 1 to about 20 carbon atoms; wherein (X6) is a halide, hydride, or alkoxide; and wherein â€œnâ€  is a number from 1 to 3 inclusive; wherein said treated solid oxide compound comprises fluorine, boron, and a solid oxide compound; wherein said solid oxide compound comprises silica.
