Abstract (en)

[origin: CA2655040A1] Proposed are lubricant compounds with a good shear stability defined by t he loss of the kinematic viscosity at 100 °C, containing base oil and a synt hetic complex ester, the complex ester having a kinematic viscosity at 40°C of greater than 400 and up to 50,000 mm2/s and being obtained by conversion of a) polyols and monocarbonic acids and dicarbonic acids, or of b) polyols and mono-alcohols and dicarbonic acids, or of c) polyols and mono-alcohols a nd monocarbonic acids and dicarbonic acids. In addition the use of the said lubricant compounds containing the complex esters as oils for vehicle transm ission, axles, industrial drives, compressors, turbines or engines is propos ed.
