Claim Text:
1. An elastomer composition comprising an emulsion which comprises 25-30 weight % of acrylonitrile, 62-71 weight % of butadiene, and 4-8 weight % of unsaturated carboxylic acid (total 100 weight %), wherein: (i) the unsaturated carboxylic acid comprises a first fraction of substituents and a second fraction of substituents, the second fraction being residual with respect to the first fraction, the first fraction of substituents forming cross-links via bonds with each other, the second fraction of substituents being unreacted; (ii) the elastomer composition, so cross-linked, has a Mooney viscosity (ML (iii) the elastomer composition does not contain sulfur cross-linking agents or sulfur vulcanization accelerators.
