ABSTRACT:
Abrasion-resistant vulcanized rubber compositions which are also resistant to heat build-up are provided which are useful as tire treads and subtreads for vehicles, e.g., automobiles. The compounds comprise the vulcanizate of a rubber polymer, a finely-divided reinforcing siliceous pigment, and an organic coupling agent having at least one nitrogen functional group that bonds to the siliceous pigment and at least one sulfur functional group that bonds to the rubber polymer.
