The catalyst dichlorobis(acetylacetone)zirconium was intercalated into montmorillonite (MT) together with AlEt 2 Cl as a cocatalyst. Reacting ethylene in the presence of this catalyst yields α ‐olefin oligomers with over 80% selectivity. [ rac ‐Et(Ind) 2 ZrCl 2 ]/MAO was then added to form a dual functional catalyst system. An MT particle‐dispersed polyethylene composite was prepared by copolymerization of the in‐situ produced oligomers with ethylene using this dual system.
