Abstract

Ethylene polymerization was performed using a series of 2-[1-(2,6-dibenzhydrylphenylimino)ethyl]-6-[1-(arylimino)ethyl]pyridyliron(II) chlorides with the activity in the range of 107 g PE mol−1 (Fe) h−1, which is the highest observed in iron procatalysts at elevated reaction temperatures such as 80 °C in the presence of MMAO and 60 °C in the presence of MAO, without any trace of ethylene oligomerization.
