Abstract: The process includes providing an aqueous mixture including perfluorinated monomers, a fluoroalkyl sulfinic acid or salt thereof, and an oxidizing agent capable of oxidizing the fluoroalkyl sulfinic acid or salt thereof and polymerizing the perfluorinated Nmonomers under free radical conditions to provide an aqueous dispersion of the fluoropolymer. The fluoroalkyl group has from one to three carbon atoms. The amount of perfluorooctanoic acid or salt thereof in the aqueous dispersion of the fluoropolymer as polymerized is not more than 25 nanograms per gram of the fluoropolymer. A fluoropolymer made by the process is also described.

Abstract: Described herein are compounds according to Formula (I) wherein Rf is a perfluorinated divalent group comprising 2 to 12 carbon atoms; and Z is selected from —CH═CH2, and —CH2CH═CH. A method of making the compound from a functionalized vinyl ether and ammonia is disclosed. In one embodiment, the functionalized triazine-containing compound is used in the polymerization of a fluoropolymer. In another embodiment, the functionalized triazine-containing compound is used in a curable fluoropolymer composition and cured to form articles.
