Abstract: Method of reducing the amount of a fluorinated acid or its salts from a fluoropolymer, the method comprises: (i) providing a composition containing particles of the fluoropolymer, (ii) contacting the fluoropolymer particles with a treatment composition comprising at least one organic liquid; and, optionally, further comprising (iii) isolating, washing and subjecting the fluoropolymer to drying treatment, and wherein the fluoropolymer contains units derived from tetrafluoroethene (TFE) and is selected from the group of fluoroelastomers and the group of fluoropolymers having a melting point of less than 150° C. Also provided are fluoropolymer and compositions containing such polymers that are essentially free of fluorinated acids and their salts.

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 polymerizing 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.
