LUBRICANT COMPOSITION WITH AN IMPROVED VISCOSITY CHARACTERISTIC AT LOW OPERATING TEMPERATURE

LUBRICANT COMPOSITION WITH AN IMPROVED VISCOSITY CHARACTERISTIC AT LOW OPERATING TEMPERATURE

A lubricant composition with a comb polymer and a synthetic base oil has improved viscosity characteristics at low operating temperatures. In addition, a comb polymer can be used 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...

Zusammenfassung:A lubricant composition with a comb polymer and a synthetic base oil has improved viscosity characteristics at low operating temperatures. In addition, a comb polymer can be used 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.
