Perfluoroelastomer compositions are provided which have excellent high temperature properties. The perfluoroelastomer component of the compositions are copolymers having a plurality of carbonyl-containing functional groups and copolymerized monomer units comprising a perfluoroolefin, a perfluoro(vinyl) ether and a nitrile-containing cure site monomer. The curative component is other than an organotin compound and includes peroxides, ammonium salts, aromatic amino compounds, bisamidrazones, and bisamidoximes.
