Abstract

L'invention concerne des compositions carboxyliques hydrocarbyle substituées et des dérivés de celles-ci comme agents améliorants la dispersion/viscosité, destinés à des compostions d'huiles lubrifiantes et de carburants. Des compostions carboxyliques sont dérivées (A) d'un polymère hydrocarboné ayant un Mn compris entre environ 20,000 et environ 500,000, et (B) un composé carboxylique α,β-insaturé préparé par la réaction (1) d'un composé actif de méthylène de formule (I), et (2) un composé carbonyle de formule générale (II), dans laquelle Ra représente un H ou un hydrocarbyle et Rb désigne un élément du groupe comprenant un H, un hydrocarbyle et (III), dans lequel chaque R' représente, de manière indépendant, un R ou un OR et chaque R désigne, de manière indépendante, un H ou un groupe hydrocarbyle; ainsi qu'un alkyle inférieur, des acétals, des cétals, des hémiacétals et des hémicétals du composé carbonyle (2). Des compositions carboxyliques dérivées sont obtenues par réaction des compositions carboxyliques avec un réactif sélectionné dans le groupe comprenant (a) des amines caractérisées par la présence dans leur structure d'au moins un groupe H-N< condensable, (b) d'alcools, (c) de métaux réactifs ou de composés métalliques réactifs, et (d) une combinaison d'au moins deux de l'un quelconque des composés (a) à (c), les composants de (d) mis en réaction avec la composition carboxylique de manière simultanée ou séquentielle, dans un ordre quelconque.
