Abstract
A method for producing an α-olefin oligomer composition includes: an oligomerization step A1 of oligomerizing an α-olefin with a metallocene catalyst to obtain an oligomer (a); a distillation separation step A2 of distilling and separating the oligomer (a) to obtain a high molecular weight fraction (a1) and a low molecular weight fraction (a2); an oligomerization step B1 of oligomerizing an α-olefin oligomer containing the low molecular weight fraction (a2) with an acid catalyst to obtain an oligomer (b); and a mixing step C of mixing a portion of the oligomer (a) or a hydrogenated product thereof and a portion or a whole of the oligomer (b), an isomer thereof, or a hydrogenated isomer thereof.
