    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 X2C═CX(CF2)m(CH2)n[O—(CX2)p]q—[O—(CX2)r]s−[O—(CX2—CX2)]t—[(O)w—(CX2)u]v—[CH2]z—Y. The method also provides for isolating the highly fluorinated polymer and post-fluorinating the isolated highly fluorinated polymer.

    Abstract: The present disclosure provides a process for removing fluoroorganic acidic compounds from an emulsion of fluoroorganic polymer particles, the process comprising the following steps: (i) forming a mixture of a. an emulsion comprising fluoroorganic polymer particles, at least one fluoroorganic acidic compound and at least one protic solvent, with b. at least one alkylamine; (ii) reacting the fluoroorganic acidic compound with the alkylamine to form a hydrophobic ionic compound comprising the anion of the fluoroorganic acidic compound and the cation of the alkyl amine; (iii) separating the mixture into a first phase comprising the at least one protic solvent and no greater than 80% by weight, preferably no greater than 50% by weight of the total amount of the at least one fluoroorganic acidic compound initially present in the solution in step (i); and a second phase comprising the hydrophobic ionic compound; (iva) removing the first phase from the second phase; and then (va) removing the fluoroorganic polymer particles from the second phase and/or the first phase, or (ivb) removing the fluoroorganic polymer particles from the second phase and/or the first phase, and then (vb) removing the first phase from the second phase.
