RUBBER COMPOSITION AND TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition enhancing low loss property and breaking strength in a rubber composition containing an inorganic filler such as silica.SOLUTION: A polar group is introduced by reacting a double bond part of a compound represented by the formula (1) and a double bond part of a diene rubber during mixture, and compatibility with a polar group of an inorganic filler, especially silanol group on a silica surface in the case of silica is enhanced. Therefor, adhesiveness between rubber and inorganic filler is enhanced, and a rubber molded body such as a tire excellent in low loss property is provided.SELECTED DRAWING: None
