Provided is a rubber composition that contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one bisanilino compound represented by formula (I). In formula (I), R1 and R2 each represent, independently of one another, a hydrogen atom or an alkyl group having a carbon number of 1-6, m and n each represent an integer of 0 or 1, A1 represents an alkylene group having a carbon number of 1-7, A2 represents an alkylene group having a carbon number of 1-8, X1 represents an oxygen atom, a sulfur atom, or an -NR3- group, and X2 represents an oxygen atom, a sulfur atom, or an -NR4- group, where R3 and R4 each represent a hydrogen atom or an alkyl group having a carbon number of 1-4, or collectively form an alkylene group having a carbon number of 1-4.
本发明提供了一种橡胶组合物,该组合物含有至少一种选自天然橡胶和二烯基合成橡胶的橡胶成分,以及至少一种由式(I)表示的双苯胺化合物。在式 (I) 中,R1 和 R2 各自独立地代表氢原子或碳原子数为 1-6 的烷基,m 和 n 各自代表 0 或 1 的整数,A1 代表碳原子数为 1-7 的亚烷基,A2 代表碳原子数为 1-8 的亚烷基、X1 代表氧原子、硫原子或 -NR3- 基团,X2 代表氧原子、硫原子或 -NR4- 基团,其中 R3 和 R4 各自代表氢原子或碳原子数为 1-4 的烷基,或共同形成碳原子数为 1-4 的亚烷基。
