Abstract

A compound represented by the formula:

wherein R is selected from the group consisting of (i) substituted or unsubstituted alkyl with C=0 to 12 inclusive; (ii) substituted or unsubstituted aryl; and (iii) substituted and unsubstituted alkylaryl;
wherein X 1 , X 2 , X 3 and X 4 are each selected from the group consisting of alkyl, aryl, alkylaryl groups and hydrogen; wherein R 1 , R 2 , R 3 , and R 4 are each selected from the group consisting of alkyl, aryl, alkylaryl groups and hydrogen and R 2 and R 3 may optionally be bridged by a polymethylene group; wherein when C=0 in R, the combined group R 1 R 2 is the same as the combined group R 3 R 4 ; and wherein when C=1 in R, each of R 1 , R 2 , R 3 , and R 4 are hydrogen.

First claim

The invention claimed is:

1. An antidegradant composition comprising N,N′-(ethane-1,2-diyl)bis(N-phenylbenzene-1,4-diamine).

2. A lubricant composition comprising a lubricant and the antidegradant composition of claim 1 .

3. A vulcanizable elastomeric formulation comprising an elastomer and the antidegradant composition of claim 1 .

4. The formulation of claim 3 wherein the antidegradant composition is present in an amount of from 0.1 to 20.0 parts per 100 parts elastomer.

5. The formulation of claim 4 wherein the antidegradant composition is present in an amount of from 0.1 to 5.0 parts per 100 parts elastomer.

6. A vulcanized elastomeric article with at least one component formed from the vulcanizable elastomeric formulation of claim 3 .

7. The vulcanized elastomeric article of claim 6 wherein said vulcanized elastomeric article is a vehicle tire.

8. The vehicle tire of claim 7 wherein said component is a sidewall.

9. A combustible fuel composition comprising a combustible fuel and the antidegradant composition of claim 1 .

10. A fuel additive composition comprising a fuel additive and the antidegradant composition of claim 1 .

11. The antidegradant composition of claim 1 , further comprising N,N′-(butane-2,3-diyl)bis(N-phenylbenzene-1,4-diamine).

12. N,N′-(ethane-1,2-diyl)bis(N-phenylbenzene-1,4-diamine).
