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.

L'invention se rapporte à la préparation d'un oligomère d'alpha-oléfine par mise en contact d'un monomère d'alpha-oléfine contenant environ de 6 à 20 atomes de carbone avec un système catalyseur comprenant du trifluorure de bore, un promoteur protique et un constituant organique de type sulfone, sulfoxyle, carbonate, thiocarbonate ou sulfonate. Il est possible de produire un oligomère contenant jusqu'à 50 % de dimère ou plus, en régime de conversion élevée, de température de réaction modérée, et pour des temps de réaction brefs qui sont acceptables.
