摘要： The invention provides a rubber composition prepared by mixing, per 100 parts by mass of a rubber component comprising at least 50% by mass of a diene-based rubber, from 20 to 150 parts by mass of a filler, and from 0.05 to 30 parts by mass of a compound A which has a specific guanidine structure and has a functional group reactive with the diene-based rubber. The rubber composition improves both a high elastic modulus and a low tan δ. The invention also provides a pneumatic tire using the rubber composition.

摘要： Provided is a rubber composition that has better weather resistance than conventional rubber compositions and can inhibit surface discoloration of a rubber article. The rubber composition contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one amine compound represented by formula (I) shown below. In formula (I), R1 and R2 each represent, independently of one another, an alkyl group having a carbon number of 1-10, an aralkyl group, or a phenyl group, and A represents an alkylene group having a carbon number of 6-30 that may include an interposed phenylene group.

摘要： Provided is a rubber composition that has better weather resistance than conventional rubber compositions and can inhibit rubber article surface discoloration. The rubber composition contains at least one rubber component selected from natural rubber and diene-based synthetic rubbers and, blended therewith, at least one bisphenyldiamine compound represented by formula (I). In formula (I), R1, R2, R5, and R6 each represent, independently of one another, a hydrogen atom, an alkyl group having a carbon number of 1-10, or a phenyl group, but R1 and R2 do not both simultaneously represent a hydrogen atom and R5 and R6 do not both simultaneously represent a hydrogen atom, R3 and R4 each represent, independently of one another, an alkyl group having a carbon number of 1-8 or an aralkyl group, A represents an alkylene group having a carbon number of 1-12, and l, m, and n each represent an integer of 0 or 1.
