Patent ID: 8501872

Claim:
A curable composition comprising A) a fluoroelastomer comprising copolymerized units of i) a first monomer selected from the group consisting of vinylidene fluoride and tetrafluoroethylene and ii) a cure site monomer having a cure site selected from the group consisting of azide, sulfonyl azide and carbonyl azide groups; and B) a curative having the formula X—(CH 2 ) n —R—(CH 2 ) m —X, wherein X is an alkyne group or a nitrile group, n, m are independently 1 to 4, and R is selected from the group consisting of i) a C 3 -C 10 fluoroalkylene group, ii) a C 3 -C 10 fluoroalkoxylene group, iii) a substituted arylene group, iv) an oligomer comprising copolymerized units of vinylidene fluoride and perfluoro(methyl vinyl ether), v) an oligomer comprising copolymerized units of vinylidene fluoride and hexafluoropropylene, vi) an oligomer comprising copolymerized units of tetrafluoroethylene and perfluoro(methyl vinyl ether), and vii) an oligomer comprising copolymerized units of tetrafluoroethylene and a hydrocarbon olefin.
