Abstract: Described are methods of making a curable fluoropolymer having repeating units derived from vinylidenfluoride (VDF) and at least one perfluorinated monomer selected from hexafluoropropene (HFP), tetrafluoroethene (TFE), a perfluorovinyl ether (PAVE), a perfluoroallylether (PAAVE) or a combination thereof. The method includes polymerising the monomers in an aqueous medium in a radical reaction containing one or more reaction initiators, one or more chain transfer agent containing one or more halogens selected from iodine, bromine or a combination thereof and one or more non-fluorinated aliphatic polyhydroxy emulsifiers. The polymerization is carried out without adding a fluorinated emulsifier. Also provided are curable fluoropolymers obtainable by such methods and cured fluoropolymers obtainable by curing the curable fluoropolymers, and their applications.

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: Provided are methods for removing a perfluorinated alkanoic acid from solutions containing the perfluorinated alkanoic acid and a fluorinated alkoxy acid. These methods include contacting the first solution with an anion-exchange resin to produce a second solution and a resultant anion-exchange resin having perfluorinated alkanoic acid adsorbed thereto, wherein the perfluorinated alkanoic acid is present in the first solution at a first concentration and is present in the second solution at a second concentration which is lower than the first concentration, and separating the second solution from the resultant anion-exchange resin.
