ABSTRACT:
In a rubbery composition in which a silica containing material is utilized as a reinforcing agent, the hysteresis of the rubbery composition is improved by incorporating the silica containing material into the rubbery composition in the form of zinc modified silica. The zinc modified silica provides an improved reinforcing agent which improves the hysteresis of the rubbery composition when the rubbery composition containing the zinc modified silica is cured.
