Abstract

A rubber compound is described containing as a reinforcing filler a layered silicate which is obtained by excessive leaching of a smectitic layered silicate with mineral acids. The rubber compound further contains at least one diene polymer or copolymer and a coupler containing groups reactive with the filler. There is also described a method for production of the rubber compound and molded articles produced from the rubber compound.
