Abstract
Elastomer isoprene rubber compositions contain an effective amount of a polyfunctional coupling system (A) as an inorganic-elastomer filler coupling agent, and (B) at least one elastomer of natural or synthetic rubber; (C) an inorganic filler as reinforcing filler; (D) other conventional constituents or additives comprising one or more vulcanizing agent(s), the polyfunctional coupling system being of the constituents (A1) and (A2): (A1) is at least one coupling agent selected from among the functionalized organosilicon compounds of formula (I): [(G)SiO][(G)SiO][GSiO][Si][(G)(G)(Z—CO—N═N—CO-A)SiO]and (A2) is at least one coupling agent selected among polysulfurated 'symmetric' silanes, or sulfurated 'asymmetric' silanes.
