Oligomers of olefins containing from 3 to about 6 carbon atoms such as dimers may be obtained in a more highly branched chain compound by effecting the oligomerization at temperatures in the range of from about 50.degree. to about 350.degree. C. and a pressure in the range of from about 100 to about 2500 psig in the presence of a catalyst comprising a fluorided aluminum phosphate. The catalyst may be prepared by impregnating an aluminum phosphate with a fluorine-containing compound in an aqeous or nonaqueous medium, drying, calcining and recovering the desired catalyst.
