摘要： An object of the invention is to provide a solid polyaluminoxane composition suitably used as a cocatalyst and a catalyst carrier in combination with an olefin oligomerization or polymerization catalyst, without the use of solid inorganic carriers such as silica. The solid polyaluminoxane composition of the invention includes a polyalkylaluminoxane and a trialkylaluminum, and has a solubility in n-hexane at 25° C. of less than 0.50 mol % as measured by a specific method (i), a solubility in toluene at 25° C. of less than 1.0 mol % as measured by a specific method (ii), and a 13 mol % or more molar fraction of alkyl groups derived from the trialkylaluminum moieties relative to the total number of moles of alkyl groups derived from the polyalkylaluminoxane moieties and the alkyl groups derived from the trialkylaluminum moieties as measured with respect to tetrahydrofuran-d8 soluble components by a specific method (iii).

摘要： 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 α-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.
