Murray, R E

This patent describes an oligomerization or cooligomerization process comprising passing ethylene or a mixture of ethylene and propylene in contact with a catalyst, in the liquid phase, the catalyst comprising the reaction product of (i) a transition metal compound wherein the transition metal is selected from the group consisting of nickel, chromium, cobalt, iron, and copper, and mixtures thereof; (ii) in the event that (a) the transition metal is not in the oxidation state of zero or (b) the transition metal compound does not have a hydride or an alkyl, alkenyl, alkynyl, or aryl group bonded to the transition metal, a catalyst activator consisting of a compound or compounds capable of transferring a hydride or an alkyl, alkenyl, alkynyl, or aryl group from itself to the transition metal/ligand.
