Natta and Ziegler utilised trimethylaluminium (TMA) as a co-catalyst, and it was not until the mid-1970s that Kaminsky discovered the utility of MAO for catalysis (see Kaminsky catalyst).
Catalytic systems based on soluble catalysts, the metallocenes, were reported in 1976 by Walter Kaminsky and Hansjörg Sinn.
