The invention concerns a process for producing synthetic oils and an olefinic polymer product which is useful as a synthetic oil or a part thereof. According to the process, olefinic hydrocarbons are polymerized in order to form an oil product having a high viscosity index and low pour point. According to the invention, the olefinic hydrocarbons used comprise C8-24 olefins with an internal double bond, which are subjected to a polymerization reaction with lower olefins, in particular 1- and 2-butenes. The reaction is carried out in the presence of an initiator system, which contains a compound of general formula (I) R2AlCl, wherein R represents halogen or an alkyl group containing 1 to 6 carbon atoms, in order to produce a polymerization product, and the polymerization product is separated from the reaction mixture in order to form a synthetic oil. |
