ABSTRACT:
For polymerizing unsaturated hydrocarbons into oligomers with acid catalysts, there are employed liquid catalyst compositions containing a Bronsted acid and a sulfone of formula R--SO.sub.2 --R', wherein R and R' are each separately a monovalent radical containing from 1 to 8 carbon atoms or form together a divalent radical having from 3 to 12 carbon atoms, the acid concentration being at least 10.sup.-.sup.5 moles per liter of sulfone and at most the saturation concentration without exceeding 5 moles per liter of sulfone. The catalysts may be dispersed in an inert hydrocarbon solvent and Lewis acids may also be added.
