Title
(EN) HIGH VISCOSITY BASE FLUIDS BASED ON OIL COMPATIBLE POLYESTERS PREPARED FROM LONG-CHAIN EPOXIDES
(FR) FLUIDES DE BASE À VISCOSITÉ ÉLEVÉE À BASE DE POLYESTERS COMPATIBLES AVEC L'HUILE PRÉPARÉS À PARTIR D'ÉPOXYDES À LONGUE CHAÎNE
Abstract
(EN) The present invention is directed to polyesters, a method for their preparation and their use as high viscosity base fluids. It is further directed to lubricant compositions comprising such polyesters and to the use of such compositions as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids or as hydraulic oils.
(FR) La présente invention concerne des polyesters, un procédé pour leur préparation et leur utilisation en tant que fluides de base à viscosité élevée. L'invention concerne en outre des compositions lubrifiantes comprenant lesdits polyesters et l'utilisation de ces compositions en tant que fluides pour transmission automatique, fluides pour transmission manuelle, fluides pour transmission à variation continue, formulations d'huile pour engrenages, formulations d'huile pour engrenages industriels, formulations de fluide d'essieu, fluides pour boîte de vitesses à double embrayage, fluides pour boîte hybride dédiée ou en tant qu'huiles hydrauliques.
