Abstract

L’invention concerne une composition de caoutchouc qui comprend un élastomère diénique, une charge renforçante comprenant plus de 50% en masse d’une silice, un système de réticulation, un agent de modification portant une fonction imidazole N-substituée et un motif contenant un groupe réactif vis-à-vis de l’élastomère diénique et le cas échéant un agent de couplage silane pour lier l’élastomère diénique à la silice, la quantité totale de l’agent de modification et de l’agent de couplage silane représente plus de 5% en masse de la quantité de la silice, le ratio entre la quantité de l’agent de modification et la quantité totale de l’agent de modification et de l’agent de couplage silane est supérieur à 0.5, les quantités étant exprimées en pce.The invention relates to a rubber composition which comprises a diene elastomer, a reinforcing filler comprising more than 50% by weight of a silica, a crosslinking system, a modifying agent bearing an N-substituted imidazole function and a unit containing an N-substituted imidazole function. group reactive towards the diene elastomer and optionally a silane coupling agent to bind the diene elastomer to the silica, the total amount of the modifying agent and the silane coupling agent represents more of 5% by mass of the amount of silica, the ratio between the amount of the modifying agent and the total amount of the modifying agent and the silane coupling agent is greater than 0.5, the amounts being expressed in pce.
