RUBBER COMPOSITION, TIRE, BISANILINO COMPOUND AND ANTI-AGING AGENT

摘要

Provided is a rubber composition which can suppress coloration of the surface of a rubber article by having better weather resistance than conventional rubber compositions. This rubber composition is characterized by being formed by mixing at least one bisanilino compound represented by expression (I) [in the expression, R1 and R2 independently represent a hydrogen atom or an alkyl group of 1-6 carbon atoms; m and n represent the integers 0 or 1; A1 represents an alkylene group of 1-7 carbon atoms; A2 represents an alkylene group of 1-8 carbon atoms; X1 represents an oxygen atom, a sulfur atom or an -NR3-group; X2 represents an oxygen atom, a sulfur atom or an -NR4-group; here, R3 and R4 are a hydrogen atom or an alkyl group of 1-4 carbon atoms, or R3 and R4 optionally combine to form an alkylene group of 1-4 carbon atoms] with at least one rubber component selected from natural rubbers and diene-based synthetic rubbers.
