Abstract
Compositions comprising a fluoropolymer derived from a nitrogen-containing cure site monomer, a catalyst composition which comprises at least one anionic functional group and at least one cationic functional group having the formula QR', wherein Q is selected from phosphorous, sulfur, nitrogen, arsenic, or antimony, wherein each R′ is independently selected from hydrogen and a nonfluorinated, partially fluorinated, or perfluorinated, C-Calkyl, aryl, aralkyl, or alkenyl group, and wherein k is the valence of Q plus one; wherein the catalyst composition is a compound or the precursors thereof added separately or as a mixture; and a composition of the formula: R″SOwherein each R″ is C-Calkyl, aralkyl, the two R″ groups together form a heterocyclic C-Ccycloalkyl, aryl, or aralkyl, each R″ can be fluorinated, and x is 1 or 2. Also provided are methods of making a fluoropolymer and fluoropolymer articles containing fluoropolymer compositions.
