Abstract
This invention relates to curable fluoroelastomer compositions comprising a) fluoroelastomers having either nitrile, alkyne or azide cure sites and b) fluorinated curatives containing diazide, dinitrile or dialkyne groups for reacting with cure sites on the fluoroelastomer. Fluoroelastomers having azide cure sites form crosslinks with curatives having dinitrile or dialkyne groups. Fluoroelastomers having nitrile or alkyne cure sites form crosslinks with curatives having diazide groups.
