Abstract

L’invention concerne une composition de caoutchouc qui comprend un élastomère diénique fortement saturé fonctionnel, copolymère qui contient des unités éthylène, des unités d’un 1,3-diène et qui porte des groupes pendants contenant une fonction imidazole N-substituée, les unités éthylène représentant plus de 50% en mole des unités de répétition constitutives de l’élastomère diénique fortement saturé fonctionnel, un système de vulcanisation, une charge renforçante qui contient une silice, et un hydrate d’un sel de thiosulfate inorganique. Une telle composition présente des propriétés d’hystérèse et de cuisson améliorées.
