CA 2752867

A composition is provided for use as a friction modifier for an automatic transmission, comprising a long chain hydrocarbyl amine having one or two additional groups on one or two different amine nitrogen atom thereof of the structure -R3-C (=0) X (R4) c. R3 is an alkylene group or a group comprising a group of 1-4 carbon atoms or a chain of 2 to 9 carbon atoms interrupted by one or two nitrogen or oxygen atoms within the chain; X is nitrogen or oxygen, and R4 is a long chain hydrocarbyl group, or H, or -R3-NHR5. The compound does not contain a primary amino group.

Composition utilisée comme modificateur de frottement dans une boîte de vitesse automatique, qui comprend une amine d'hydrocarbyle à chaîne longue comptant un ou deux groupes supplémentaires sur un ou deux atomes d'azote d'amine différente de la structure -R3-C(=O)X(R4)c. R3 est un groupe alkylène ou un groupe comprenant une chaîne de 2 à 9 atomes de carbone interrompue par un ou deux atomes d'azote ou d'oxygène, X est azote ou oxygène, et R4 est un groupe hydrocarbyle à chaîne longue, ou H, ou -R3-NHR5. Le composé ne contient pas de groupe amino primaire.
