Abstract

Alpha-olefin oligomers are produced by oligomerizing an alpha-olefin monomer with a catalyst system comprising boron trifluoride, a protic promoter, and a modifier which is (a) at least one 1,3-dioxolane, or (b) at least one 1,3-dioxane, or (c) a combination of (a) and (b). Use of these modifiers in the BF.sub.3 -catalyzed oligomerization makes it possible to modify the promoted catalytic reaction so that product containing as much as 50% or more of dimer can be produced at high conversions, at modest reaction temperatures, and in short reaction periods.
