The invention concerns a process for producing synthetic oils, wherein olefinic hydrocarbons are polymerized to form an oily product having a high viscosity index and a low pour point. According to the invention, higher linear alpha-olefins containing 6 to 24 carbon atoms are reacted with a hydrocarbon composition 15 to 80 % by weight of 1-butene, 5 to 50 % by weight of 2-butenes, and about 10 % by weight or less of isobutylene in the presence of an initiator system to produce a copolymer-containing reaction mixture, and the copolymer is separated from the reaction mixture. By means of the invention it is possible to prepare high-quality synthetic oils from an inexpensive raw material such as Raffinate II emanating from the production of MTBE or polyisobutylene.
