Zusammenfassung:A process to produce a first catalyst composition is provided. The process comprises contacting at least one first organometal compound and at least on e activator to produce the first catalyst composition. The activator is select ed from the group consisting of aluminoxanes, fluoro-organo borates, and treate d solid oxide components in combination with at least one organoaluminum compound. In another embodiment of this invention, a process to produce a second catalyst composition for producing bimodal polymers is provided. The process comprises contacting at least one first organometal compound, at lea st one activator, and at least one second organometal compound to produce the second catalyst composition. The first and second catalyst compositions are also provided as well as polymerization processes using these compositions t o produce polymers.
