An oligomerization catalyst for α-olefins, comprising
[A] at least one nickel compound selected from the group consisting of a nickel salt of organic acid, a nickel salt of inorganic acid and a complex compound of nickel;
[B] an organoaluminum oxy-compound having at least 3 aluminum atoms in the molecule; and
[C] a trivalent phosphorous compound represented by the general formula PR¹R²R³ wherein R¹ to R³ are each independently a hydrocarbon group or substituted hydrocarbon group of 1 to 10 carbon atoms.
A process for oligomerizing α-olefin, wherein α-olefin is oligomerized in the presence of the catalyst mentioned above.
