Abstract (en)
[origin: WO2018083027A1] The invention relates to a lubricant composition comprising a comb polymer and a synthetic base oil. The lubricant composition has improved viscosity characteristics at low operating temperatures. The invention also relates to the use of a comb polymer for producing a lubricant having an R-factor of less than or equal to 8, wherein the R-factor is defined as the ratio of the kinematic viscosity at -20°C and the kinematic viscosity at +20°C.
