Abstract

L'invention concerne des additifs modifiant le frottement utiles dans des compositions pour boîtes de vitesses, notamment des liquides de boîtes de vitesses automatiques. L'additif comprend un composant 1 formé seul par condensation d'une polyamine telle qu'une pentamine tétraéthylénique avec un monoacide aliphatique tel qu'un acide isostéarique, ou un mélange, et/ou un sel, du composant-1 et d'un composant 2, le composant 2 étant un ester acide formé par réaction d'un hétérodialcanol tel que thiobiséthanol et d'un acide ou anhydride dicarboxylique à substitution hydrocarbyle, tel qu'un anhydride succinique octadécényle.
