Polymerization catalyst compositions and processes to produce polymers and bimodal polymers

A process to produce a first catalyst composition, said process comprising contacting at least one first organometal compound and at least one activator;

• wherein said first organometal compound is represented by the formula;
• R2CpM1—O—M2CpR2
• wherein M1 is selected from the group consisting of titanium, zirconium, and hafnium;
• wherein M2 is selected from the group consisting of a transition metal, a lanthamide, an actinide, a Group IIIB metal, a Group IVB metal, a Group VB metal, and a Group VIB metal;
• wherein Cp is independently selected from the group consisting of cyclopentadienyls, indenyls, fluorenyls, substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls;
• wherein substituents on said substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls of Cp 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, germanium, and hydrogen;
• wherein R is 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;
• and
• wherein said activator is selected from the group consisting of aluminoxanes, fluoro-organic borate compounds, and treated solid oxide components in combination with at least one organoaluminum compound.
