Beschreibung
Zusammenfassung:	A rubber composition based on one or more diene elastomer(s), on at least one reinforcing filler, on at least one coupling agent, on at least one chemical crosslinking system, wherein the reinforcing filler comprises silica in the form of essentially spherical nanoparticles, the specific surface area of this silica ranging from 30 m2/g to 250 m2/g. Also disclosed is a process for producing such a composition and also semi-finished or finished articles comprising at least one such composition.
