  • Patent number: 5545693
    Abstract: Blends of a perfluoroelastomer with a nitrile containing polyperfluoroether are described. The addition of the polyperfluoroether often improves the properties, processability and/or low temperature properties of the perfluoroelastomer. It is preferred if the perfluoroelastomer contains nitrile groups so that the two polymers can cocure, thereby retarding separation of the polyperfluoroether from the perfluoroelastomer.
