Abstract

L'invention concerne une huile lubrifiante comprenant un copolymère aléatoire d'une alpha -oléfine/composé vinyle aromatique, dans laquelle le copolymère présente une viscosité se situant dans une plage spécifique et comporte de l'éthylène, un composé vinyle aromatique, et éventuellement une alpha -oléfine. Cette huile lubrifiante possède d'excellentes caractéristiques de viscosité, de stabilité thermique, de stabilité à l'oxydation, de résistance à l'abrasion, et de compatibilité avec des additifs pour huile lubrifiante. Le copolymère aléatoire présentant une plage de viscosité différente est utile comme additif d'indice de viscosité et agent de compatibilisation pour une huile lubrifiante. L'invention concerne également une composition d'huile lubrifiante renfermant une huile de base ainsi que l'additif d'indice de viscosité ou l'agent de compatibilisation. L'invention concerne d'autre part une composition de fioul contenant un additif de fluidité à base du copolymère aléatoire précité présentant une plage de viscosité différente, et un fioul de fraction moyenne présentant un point d'ébullition compris entre 150 et 400 DEG C. La composition de fioul empêche une augmentation de viscosité du fioul de fraction moyenne, abaisse le point de colmatage et le point d'écoulement dans un filtre à basse température, et inhibe l'abrasion du gicleur.
