Beschreibung
Zusammenfassung:	Provided are low molecular weight polyalkyl acrylate polymers, the method and the use as high viscosity base fluids thereof. It is further directed to lubricant compositions comprising such low molecular weight polyalkyl acrylate polymers 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. L'invention concerne des polymères de polyalkyle acrylate de faible poids moléculaire, un procédé associé ainsi que leur utilisation en tant que fluides de base à viscosité élevée. L'invention concerne en outre des compositions lubrifiantes comprenant lesdits polymères de polyalkyle acrylate de faible poids moléculaire, ainsi que 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.
