摘要：
Various catalyst compositions including the contact product of at least one ansa-metallocene compound, at least one organoaluminum compound, and at least one activator-support are disclosed. Processes for forming such compositions and for forming polyolefins with such compositions are also disclosed. Metallocene compounds are also presented.
