Abstract
Official abstract text for this publication.
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), R 1 and R 2 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, A 1 represents an alkylene group having a carbon number of 1-7, A 2 represents an alkylene group having a carbon number of 1-8, X 1 represents an oxygen atom, a sulfur atom, or an —NR 3 — group, and X 2 represents an oxygen atom, a sulfur atom, or an —NR 4 — group, where R 3 and R 4 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition comprising 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) shown below where, in formula (I), R 1 and R 2 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, A 1 represents an alkylene group having a carbon number of 1-7, A 2 represents an alkylene group having a carbon number of 1-8, X 1 represents an oxygen atom or an —NR 3 — group, and X 2 represents an oxygen atom or an —NR 4 — group, where R 3 and R 4 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. 2. The rubber composition of claim 1 , wherein in the at least one bisanilino compound represented by formula (I), R 1 and R 2 are each, independently of one another, an alkyl group having a carbon number of 3-6, m and n are each 0, A 1 is an alkylene group having a carbon number of 1-4, A 2 is an alkylene group having a carbon number of 5-8, and X 1 and X 2 are each an oxygen atom. 3. The rubber composition of claim 1 , wherein a blending amount of the at least one bisanilino compound represented by formula (I) is in a range of from 0.2 parts by mass to 10 parts by mass relative to 100 parts by mass of the at least one rubber component. 4. A tire comprising a tire member comprising the rubber composition of claim 1 . 5. The tire of claim 4 , wherein the tire member is either or both of a tread and a sidewall. 6. A bisanilino compound represented by formula (I) shown below where, in formula (I), R 1 and R 2 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, A 1 represents an alkylene group having a carbon number of 1-7, A 2 represents an alkylene group having a carbon number of 1-8, X 1 represents an oxygen atom or an —NR 3 — group, and X 2 represents an oxygen atom or an —NR 4 — group, where R 3 and R 4 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. 7. An anti-aging agent for natural rubber and diene-based synthetic rubber-use comprising the bisanilino compound of claim 6 .
