Activated silane compound, rubber composition using the same and tire

摘要

The present invention relates to an activated silane compound obtained by reacting a hydrocarbyloxysilane compound with an organic metal compound in an organic solvent, and enhancing interaction of silica with carbon black and improving the fracture characteristic, the abrasion resistance and the low heating property provide an activated silane compound which can be reduced in a blending amount, a rubber composition prepared by blending it as a silane coupling agent and a pneumatic tire prepared by using the above rubber composition, which is excellent in a durability, a low heating property and the like.
