Abstract:
A process to produce a catalyst composition, said process comprising contacting an organometal compound, and organoaluminum compound, and a treated solid oxide compound to produce said 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 titanium, zirconium, or hafnium; wherein (X1) is independently a cyclopentadienyl, an indenyl, a fluorenyl, substituted cyclopentadienyls, substituted indenyls, or substituted fluorenyls; wherein substituents on said substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls of (X1) are aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, silyl groups, alkyl halide groups, halides, organometallic groups, phosphorus groups, nitrogen groups, silicon, phosphorous, boron, germanium or hydrogen; wherein at least one substituent on (X1) can be a bridging group which connects (X1) and (X2); wherein (X3) and (X4) are independently 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 group, substituted phosphido groups, alkyloxide groups, substituted alkyloxide groups, aryloxide groups, substituted aryloxide groups, organometallic groups, or substituted organometallic groups; wherein (X2) is a cyclopentadienyl, an indenyl, a fluorenyl, 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, or substituted organometallic groups; wherein substituents on (X2) are aliphatic groups, cyclic groups, combinations of aliphatic groups and cyclic groups, silyl groups, alkyl halide groups, halides, organometallic groups, phosphorus groups, nitrogen groups, silicon, phosphorous, boron, germanium or hydrogen; wherein at least one substituent on (X2) can be a bridging group which connects (X1) and (X2); wherein said organoaluminum compound has the following general formula: Al(X5)n(X6)3-n wherein (X5) is a hydrocarbyl having from 1 to about 20 carbon atoms; wherein (X6) is a halide, hydride, or alkoxide; wherein â€œnâ€  is a number from 1 to 3 inclusive; wherein said treated solid oxide compound comprises at least on halogen, titanium, and a solid oxide compound; wherein said halogen is chlorine, bromine, or fluorine; wherein the solid oxide compound is alumina, aluminophosphate, aluminosilicate, aluminoborate, silica-titania, silica-zirconia or mixtures thereof.
