Abstract

L'invention concerne des additifs pour huiles ayant des propriétés à la fois dispersantes et d'amélioration de l'indice de viscosité. On fait réagir un copolymère éthylène-propylène avec du chlore et/ou un acide dicarboxylique non saturé en alpha-bêta ou un dérivé d'un tel acide et on fait réagir ensuite le produit intermédiaire résultant avec certaines amines et/ou certains alcane polyols. Application aux huiles pour moteur.
