  • Patent number: 9616421
    Abstract: The objectives of the present invention are to provide an olefin oligomerization catalyst that allows properties of particles of a polymer component by-produced in an ?-olefin production process to be obtained in such a shape that does not negatively affect a separation process for the particles and to provide a method for producing an olefin oligomer performed in the presence of the olefin oligomerization catalyst. The objectives can be achieved by the olefin oligomerization catalyst obtained by contacting (D) a transition metal compound with a preliminary contact solid catalyst component (II) obtained by contacting a solid catalyst component (I) formed by supporting (B) an organoaluminum oxy-compound (b-2) on (A) a solid carrier with (C) at least one compound selected from the group consisting of an organometallic compound (c-1), an organoaluminum oxy-compound (c-2), and a compound (c-3) that reacts with the transition metal compound (D) to form a pair of ion.
