NOVEL HYDROCARBON BASE OIL FOR LUBRICANTS WITH VERY HIGH VISCOSITY INDEX |
摘要 |
The invention concerns a novel hydrocarbon base oil for lubricants, having a viscosity index not less than 130, comprising mainly long isoparaffinic hydrocarbon chains, branched over several carbon atoms. The invention is characterised in that said chains comprise a number of carbon atoms greater than 25 and have a ratio of the number of substituents consisting of at least two carbon atoms over the number of methyl-type substituents, not less than 0.9.
