  • Process for crosslinking carboxylated nitrile rubber, hydrogenating carboxylated nitrile rubber, the crosslinked rubber and its' uses
    Patent number: 6828385
    Abstract: A process has now been discovered that permits the simultaneous crosslinking and derivation of an, optionally hydrogenated, polymer whose backbone is composed of a conjugated diene, an unsaturated nitrile and an unsaturated carboxylic acid in the presence of a coupling/condensing agent. This permits the preparation of a novel polymeric material that is an optionally hydrogenated polymer of a conjugated diene, an unsaturated nitrile and a derived unsaturated acid. It has also been found that this novel polymeric material has unexpected and valuable properties.

  • Heat-and-oil resistant polymer blends
    Publication number: 20030134979
    Abstract: A conjugate is formed by blending a polyamide with a hydrogenated carboxylated nitrile rubber at elevated temperature. The conjugate is readily formable by molding or extrusion, and it displays excellent heat, oil-resistant and barrier properties that render it suitable for use, for example, in many automotive under-the-hood applications.
