| titleOfInvention | Process for preparing fluoropolymer dispersions |
| abstract | The present invention relates to a method for preparing a fluoropolymer dispersion, the method comprising the aqueous emulsion polymerization of one or more fluorinated monomers, wherein the aqueous emulsion polymerization comprises a surfactant mixture [mixture (S )], the surfactant mixture comprising: at least one perfluorohexanoic acid or a salt thereof [surfactant (C6)] in an amount of 1 to 5 g/l relative to the aqueous medium; and at least A linear bifunctional perfluoropolyether surfactant [surfactant (PFPE)] according to formula (I) below: X p OOC-CF 2 -O-(CF 2 O) n' ( CF 2 CF 2 O) m'-CF 2 -COOX p (I) wherein: X p , the same or different from each other, are hydrogen atoms; a monovalent metal, preferably an alkali metal; or having the formula -N(R' n ) 4 an ammonium group, wherein R'n is the same or different at each occurrence, is a hydrogen atom or a C1 - C6 hydrocarbon group, preferably an alkyl group; n' and m' are independently integers > 0 such that the surface The number average molecular weight of the active agent (PFPE) is 500 to 2500, and the surfactant (PFPE) is used in an amount of 0.005 to 0.5 g/l relative to the aqueous medium. |
