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.

A heat stable siloxane-imide copolymer and a curable silicone adhesive composition comprising such a siloxane-imide copolymer is shown and described herein. The composition includes an alkenyl silicone, a silicone hydride based cross linker, hydrosilylation catalyst and additives that is curable at relatively low temperatures and shows good heat stability.
