A catalyst comprising a fluorinated gamma-alumina impregnated by a bis (cyclodiene) nickel (o) chelate, preferably bis (cyclooctadiene-1,5) nickel (o) chelate, can be used as a catalyst in the oligomerisatlon of propylene, butylene or of a propylene/butene mixture, for example the dimerisation of butene-1 and/or butene-2. |
