Reinforced rubber composition, useful for pneumatic tire, comprises conjugated diene rubber, reinforcer e.g. precipitated silica and ionic compound having ionic salt

摘要

Reinforced rubber composition comprises conjugated diene rubber, a reinforcer at 15-120 parts by weight having precipitated silica or a precipitated silica-carbon black blend, and an ionic compound having an ionic salt of an organic cation fraction and (in)organic anion fraction. An independent claim is included for a pneumatic tire comprising a component containing the reinforced rubber composition.
