RUBBER COMPOSITION AND PNEUMATIC TIRE |
| 摘要 |
An object of the present invention is to provide a rubber composition which can further improve abrasion resistance without deterioration in energy efficiency, and a pneumatic tire using the rubber composition. The rubber composition comprises a polymer mixture obtained by modifying a polymer composed of at least one of a conjugated diene compound and an aromatic vinyl compound with a compound having at least one of an ester group and a carboxyl group; at least one of triamines; and silica, the polymer mixture having a weight-average molecular weight of 1.0×103 to 1.0×105, and the triamines being a compound represented by the following formula (I):;;wherein each of RA, RB, RC, RD and RE independently represents a hydrogen atom or an alkyl group, and each of ALK1 and ALK2 independently represents an alkylene group. |
