Abstract
Alpha-olefin oligomer is prepared by contacting an alpha-olefin monomer which contains from about 6 to about 20 carbon atoms with a catalyst system comprising boron trifluoride, a protic promoter, and an organic sulfone, sulfoxide, carbonate, thiocarbonate, or sulfonate. Oligomer containing as much as 50% or more of dimer can be produced at high conversions, at modest reaction temperatures, and in acceptably short reaction periods.
