TITLE PEROXIDE CURABLE BROMINATED OR IODINATED FLUOROELASTOMER COMPOSITION CONTAINING AN N,N,N',N'-TETRASUBSTITUTED 1,8-DIAMINONAPHTHALENE ABSTRACT OF THE DISCLOSURE A peroxide-curable fluoroelastomer composition which comprises a fluoroelastomer whose interpolymerised units consist essentially of units derived from vinylidene fluoride, units derived from at least one other fluorine-containing monomer copolymerizable therewith, said monomer being a compound which contains 2-7 carbon atoms, contains no bromine atoms or iodine atoms, and contains at least as many fluorine atoms as carbon atoms, and said fluoroelastomer contains up to 3 mole percent of units derived from a bromine-containing olefin or 0,.1-2 mole percent of units derived from an iodine-containing olefin, and from about 0.05-2 parts per 100 parts fluoroelastomer of an N,N,N',N'-tetra- substituted 1,B-diaminonaphthalene having the formula: Image wherein R1, R2, R3 and R4 are independently alkyl groups of 1-6 carbon atoms, phenyl or benzyl, R1 and R2 and/or R3 and R4 can be joined to form a 5- or 6-membered heterocyclic ring in which a carbon atom can be replaced by an oxygen or a sulfur atom, R1 and R3 and/or R2 and R4 can be joined to form a heterocyclic ring of 6-20 carbon atoms in which a carbon atom can be replaced by an oxygen or a sulfur atom, X and Y are independently an alkyl group or an alkoxy group containing 1-4 carbon atoms and n is 0-3.
