Crosslinking coagents based on aromatic diimides having N-substituted allyl groups are employed in place of triallyl isocyanurate (TAIC) for the free radical curing of fluoroelastomers. The diimide coagents mix more easily with fluoroelastomers and are less likely to homopolymerize than TAIC. Thus mold fouling and sticking due to low molecular weight polymers of coagent is greatly reduced.
