Abstract: Sulfur silane coupling agents for use in tire compositions used to formulate tires or tire components which contain multiple blocked mercapto groups which are in a state of reduced activity until activated. The coupling agents are advantageously used in rubber formulations, including tire compositions, for example, for fabricating tires with low rolling resistance.

Abstract: Sulfur-containing silane coupling agents, and organic polymers containing carbon-carbon double bonds. These silanes can be carried on organic and inorganic fillers. The invention also relates to tire compositions and articles of manufacture, particularly tires, made from elastomer compositions.

Abstract: Free-flowing filler compositions containing silated cyclic core polysulfide coupling agents, and rubber and tire compositions containing the filler compositions.
