Abstract
The present invention is directed to a nitrile polymer vulcanizate having improved hot air aging characteristics. The nitrile polymer vulcanizate may be produced by admixing a composition containing: (i) a nitrile polymer; (ii) a filler; (iii) a metal salt of a secondary amine; (iv) a vulcanization system; and optionally (v) an additive selected from the group consisting of a strong base, a salt of a strong base and a weak acid, a salt of a weak acid, a carbodiimide, a polycarbodiimide and mixtures thereof.
