Abstract
Preparation of a rubber composition containing a dispersion of aligned exfoliated graphite platelets. Such rubber composition is prepared by a method comprised of a sequential combination of concentrated solvent or dry masterbatching of elastomer and exfoliated graphite platelets, followed by blending the masterbatch (after removing the solvent from the solvent based masterbatch) with additional elastomer(s) and then followed by processing the resulting rubber composition to align the dispersed exfoliated graphite platelets in a substantially parallel relation to each other. Such processing may comprise as least one of extrusion and calendaring the rubber composition. The invention further relates to a tire containing a component comprised of such rubber composition containing a dispersion of aligned exfoliated graphite platelets prepared by the aforesaid method.
