ABSTRACT:
A process for oligomerizing alpha-olefins comprising contacting in a reactor zone under reaction conditions: (a) alpha-olefins having at least three carbon atoms; (b) an alkyl aluminum bromine or iodine compound having the formula R.sub.3 Al.sub.2 X.sub.3 or R.sub.n AlX.sub.3-n, wherein n is 1 or 2; R is an hydrocarbyl group and X is a reactive halogen selected from bromine and iodine; and (c) a cocatalyst which is (i) bromine, (ii) iodine, (iii) hydrocarbyl bromide having at least one halogen group reactive with said aluminum compound or (iv) hydrocarbyl iodide having at least one halogen group reactive with said aluminum compound.
