Described herein are fluoropolymer compositions comprising a bis phthalonitrile-containing compound. In one embodiment, the bis phthalonitrile-containing compound is used to crosslink a dehydrohalogenated polymer, and optionally with a polyhydroxy curative. In another embodiment, the bis phthalonitrile-containing compound is added to a composition comprising (i) a fluorinated elastomeric gum, wherein the fluorinated elastomeric gum comprises a fluoropolymer having a cure-site and (ii) a peroxide curing system. |
