Aluminum alkyls with pendant olefins for polyolefin reactions
This invention relates to organoaluminum compounds, organoaluminum activator systems, preferably supported, to polymerization catalyst systems containing these activator systems and to polymerization processes utilizing the same. In particular, this invention relates to catalyst systems comprising a support, an organoaluminum compound and a metallocene.
1. An aluminum vinyl-transfer agent represented by the formula:
Al(R′) 3-v (R) v ,
