Abstract
Adducts of a trialkylaluminum or a dialkylaluminum hydride and diisoalkenyl benzene compounds have been discovered. Catalyst components for the polymerization of olefins have also been developed which comprise, as the cocatalyst, the reaction product of a trialkylaluminum or a dialkylaluminum hydride (e.g., diisobutylaluminum hydride) and an alkenyl-substituted benzene (e.g., diisopropenyl benzene).
