There is provided a friction modifier of the formula R1~-L-N(R2~)(R3~) wherein R1~ is a hydrocarbyl group that has a number average molecular weight (Mn) of from 500 to 5000; L is an optional linker group; and R2~ and R3~ are independently selected from H, a hydrocarbyl group and a bond to optional group L, wherein at least one of R2~ and R3~ is H or a hydrocarbyl group, with the proviso that if one of R2~ and R3~ is a hydrocarbyl group and the other of R2~ and R3~ is H, the hydrocarbyl group does not contain a terminal amine.
L'invention concerne un modificateur de coefficient de frottement repr~sent~ par la formule g~n~rale R?1´-L-N(R?2´)(R?3´), dans laquelle R?1´ d~signe un groupe hydrocarbyle ayant un poids mol~culaire moyen en nombre (Mn) compris entre 500 et 5000, L d~signe un groupe de liaison facultatif et R?2´ et R?3´ d~signent chacun un ~l~ment s~lectionn~ ind~pendamment dans l'ensemble comprenant H, un groupe hydrocarbyle et une liaison vers le groupe de liaison facultatif L. Dans cette formule, R?2´ et/ou R?3´ d~signent H ou un groupe hydrocarbyle. Toutefois, si R?2´ ou R?3´ d~signe un groupe hydrocarbyle et que l'autre R?2´ ou R?3´ d~signe H, le groupe hydrocarbyle ne contient pas d'amine terminale.
