The oligomerization of ethylene using a chromium catalyst having a phosphorus- nitrogen-phosphorus ("P-N-P") ligand is typically activated with an aluminoxane. The addition of an alkyl zinc, particularly diethyl zinc, has been fund to improve the productivity of certain oligomerization reactions. In particular, the addition of diethyl zinc to an oligomerization reaction that is activated by methylaluminoxane (MAO) improves the productivity of the reaction.
