20130153099 | TIRE TREAD BASE CONTAINING SYNDIOTACTIC-1,2-POLYBUTADIENE WITH DIVERSE CARBON BLACKS - The invention relates to a pneumatic tire having a cap/base configuration comprised of an outer tread cap rubber layer, with a tread running surface, and an underlying tread base rubber layer, where the base rubber layer contains syndiotactic polybutadiene with a diverse blend of carbon blacks. | 06-20-2013 |
20140113993 | PREPARATION OF SILICA REINFORCED RUBBER COMPOSITION AND TIRE WITH COMPONENT THEREOF - The invention relates to the preparation of a rubber composition containing a pre-treated precipitated silica and a tire having a component comprised of such rubber composition. The pre-treated silica is a precipitated silica having been pre-treated with a silica coupling agent comprised of an alkoxyorganomercaptosilane to form a precipitated silica/coupling agent composite prior to its blending with a rubber composition. The rubber composition preparation involves reacting said pretreated silica/coupling agent composite with a combination of bis(3-triethoxysilylpropyl)polysulfides in situ within the rubber composition. | 04-24-2014 |
