Abstract : A perfluoroalkylene oxide dinitrile, an aromatic dinitrile N-oxide and an aromatic trinitrile are terpolymerized to obtain a poly(perfluoroalkylene oxide) oxadiazole containing pendent aromatic nitrile groups. The fluorinated polymer product can be cured with a poly-functional nitrile N-oxide to provide elastomers that are particularly useful in aircraft applications involving use temperatures ranging from about -70F to about 400F. For example, the elastomers can be employed as fuel tank sealants, coatings, O-ring seals, diaphragms, and the like.
