Abstract
A method of making a highly fluorinated polymers and resulting aqueous mixtures. The method comprising polymerizing one or more perfluorinated monomers in an aqueous emulsion polymerization in the presence of a polymerizable fluorinated emulsifier to form a perfluorinated polymer. The polymerizable fluorinated emulsifier has the formula XC═CX(CF)(CH)[O—(CX)]—[O—(CX)]−[O—(CX—CX)]—[(O)—(CX)]—[CH]—Y. The method also provides for isolating the highly fluorinated polymer and post-fluorinating the isolated highly fluorinated polymer.
