Sterically crowded dimeric diisobutylaluminum aryloxides: Synthesis, characteristics, and application as activators in homo- and copolymerization of olefins

The paper reports the synthesis and characterization of a number of dimeric diisobutylaluminum aryloxides and their application as activators in zirconocene-catalyzed copolymerization of olefins. The correlation was established between structural features of those Al-based compounds and their activating ability in olefin polymerization.426
