Organometal catalyst compositions

A process to produce a catalyst composition, said process comprising contacting respectively organometal compound, at least one organoaluminum compound, and a fluorided solid oxide compound to produce said catalyst composition,

• 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 substitutents 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, alkyl halide groups, halides, organometallic groups, phosphorus groups, nitrogen groups, silicon, phosphorus, boron, and germanium;
• 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 at least one substitutuent on (X2) can be a bridging group which connects (X1) and (X2);
• wherein said organoaluminum compound has the general formula:
• Al(X5)n(X6)3-n
• wherein (X5) is a hydrocarbyl having from 1 to about 20 carbon atoms;
