Aluminium‐based compounds, such as R 3 Al and R 2 AlOAlR 2 , were tested as activators for the iron complex [(ArN=C(Me)) 2 C 5 H 3 N]FeCl 2 (Ar = 2,6‐diisopropylphenyl) in ethylene polymerization. Different activator/catalyst combinations produce polyethylene with differing molecular weights and molecular weight distributions, and with varying polymerization activities. The activators tested thus represent easily available and efficient cocatalysts for a late‐transition‐metal complex.
