ABSTRACT:
A catalyst composition for a process of oligomerising ethylene to produce 1-butene and/or 1-hexene wherein the catalytic composition is obtained by mixing at least one chromium compound with at least one aryloxy aluminum compound with general formula R.sub.n Al(R'O).sub.3-n where R is a linear or branched hydrocarbyl radical containing 1 to 30 carbon atoms, R'O is an aryloxy radical containing 6 to 80 carbon atoms and n is a whole number which can take the values 0, 1 or 2, and with at least one other hydrocarbyl aluminum compound selected from tris(hydrocarbyl)aluminum compounds or chlorinated or brominated hydrocarbyl aluminum compounds.
