A molybdated suednimide complex prepared by a process which comprises (a) reacting an alky! or alkeny! succLmrnide of a polyamine of formula (I) wherein R is an about C12 to C30 alkyl or alkenyl group, a and b are independently 2 or 3, and x is 0 to 10, with an eihylenicaUy unsaturated carboxylic acid or anhydride thereof; and (b) reacting the suceinimide product of step (a) with an acidic molybdenum compound. 2, The molybdated succtu.eta.mide complex of Claim 1, wherein R is about C12 to about C24 alky! or alkenyl group, a and b are each 2, and x is 2 to 5. 3, The molybdaied succinimide complex according to Claims I or 2, wherein the etbyienicaily unsaturated carboxylic acid or anhydride is an athyïenicaily unsaturated monocarboxyiic acid or anhydride thereof, 4, The molybdated sueeimmide complex according to Claims 1 or 2, wherein the ethylemcally unsaturated carboxylic acid or anhydride is an ethyle.pi.ricaliy unsaturated dicarboxylic acid or anhydride thereof
Cette invention concerne un complexe succinimide à base de molybdène obtenu par un procédé consistant: (a) à faire réagir un succinimide d'alkyle ou d'alcényle d'un polyamine de formule (I) de formule (I) - R étant est un groupe alkyle ou alcényle en C12-C30 environ; et a et b valant indépendamment 2 ou 3 et x valant de 0 à 10 - avec un acide carboxylique éthyléniquement insaturé ou un anhydride de ce dernier; et (b) à faire réagir le produit de l'opération (a) avec un composé de molybdène acide. L'invention concerne également une composition d'huile de graissage contenant au moins une quantité importante d'une huile de base à viscosité lubrifiante et (b) une faible quantité d'un complexe succinimide à base de molybdène.
