## Abstract

The invention provides articles obtained from curing a composition consisting of a polymercapto crosslinking agent, a vulcanization accelerator, an inorganic base, a nitrogen containing chelating agent, wherein the nitrogen containing chelating agent is selected from the group consisting of 1,10-phenanthroline and 2,2-bipyridyl, and polyethylenimine; and a halogenated elastomer; wherein said nitrogen containing chelating agent is soluble in said halogenated elastomer.

## Claims

### Claim at position 1

1: An article obtained from curing of a composition consisting of:
a) a polymercapto crosslinking agent,
b) a vulcanization accelerator,
c) an inorganic base,
d) a nitrogen containing chelating agent, wherein the nitrogen containing chelating agent is selected from the group consisting of 1,10-phenanthroline and 2,2-bipyridyl, and polyethylenimine; and
e) a halogenated elastomer; wherein said nitrogen containing chelating agent is soluble in said halogenated elastomer.

### Claim at position 2 (depends on 1)

2: The article of claim 1, wherein the polymercapto crosslinking agent is 2,5-dimercapto-1,3,4-thiadiazole or a derivative thereof.

### Claim at position 3 (depends on 1)

3: The article of claim 1, wherein the polymercapto crosslinking agent is 2-mercapto-1,3,4-thiadiazole-5-thiobenzoate.

### Claim at position 4 (depends on 1)

4: The article of claim 1, wherein the vulcanization accelerator is selected from the group consisting of quaternary ammonium or phosphonium salts, tertiary amines, and dihydropyridine derivatives.
