Abstract

L’invention concerne une composition lubrifiante qui comprend une huile de base minérale et un copolymère d’éthylène et de 1,3-butadiène qui contient plus de 90% à moins de 97% en mole d’unités éthylène et qui a un taux de cristallinité supérieur à 30% et inférieur à 45%. Elle peut être utilisée en tant qu’huile de moteur.A lubricating composition is provided that includes a mineral base oil and a copolymer of ethylene and 1,3-butadiene that contains greater than 90% to less than 97 mol% ethylene units and has a rate of crystallinity greater than 30% and less than 45%. It can be used as engine oil.
