Abstract
L'invention concerne un additif pour huiles. On le prépare en faisant réagir un polymère étoilé sélectivement hydrogéné ayant au moins quatre branches de polymères ou de copolymères de diènes et de monoalcénylarènes avec un acide carboxylique insaturé alpha-bêta ou un dérivé, et en faisant réagir le composé intermédiaire résultant avec une amine et/ou un polyol alcane. Application aux lubrifiants pour moteur.
