ABSTRACT OF THE DISCLOSURE Hydrogenated synthetic lubricating oils are obtained by subjecting a polymer having a substantially high viscosity and a boiling point higher than 175°C, obtained by polymerizing normal alpha-olefines having the general formula R-CH = CH2 wherein R is an alkyl radical containing from 2 up to 16 carbon atoms, in the presence of a TiCl4/polyiminoalane catalyst and under an inert atmosphere possibly containing hydrogen up to a partial pressure of 1 kg/cm2, to a hydrogenating catalytic cracking carried out at a temperature comprised between 300 and 400°C and under a hydrogen pressure of from 20 to 200 kg/cm2, the volume of liquid per volume of catalyst per hour being comprised between 0.1 and 5, said catalyst contains oxides or sulfides of metals selected from the VI to the VIII group of the Periodical System and is supported on a carrier having a weak Lewis acidity,distilling the resulting product under vacuum up to a head temperature, referred to atmospheric pressure, of 400°C and finally separating the fraction having a boiling point higher than 400°C. The oils thereby obtained present high viscosity indices, very low pour points, low viscosities at 0°F, high flash points, high thermal stability, high resistance to depolymerization and very low carbon reisu.
