Disclosed is a method for preparing fluorinated emulsion polymers that reduces or eliminates the need for fluorinated surfactants comprising the steps of: a) providing a reaction mixture comprising water, surfactant, monomer mixture comprising at least one fluorinated monomer, at least one non-fluorinated monomer having high water solubility, and optionally at least one non-fluorinated monomer having low water solubility, macromolecular organic compound having a hydrophobic cavity; and b) polymerizing said monomer mixture.
Divulgation d'une méthode pour préparer des émulsions de polymères fluorés, qui réduit ou élimine le besoin de surfactants fluorés. Cette méthode comprend les étapes suivantes : a) la réalisation d'un mélange réactionnel comprenant de l'eau, un surfactant, un mélange de monomères contenant au moins un monomère fluoré, au moins un monomère non fluoré très soluble dans l'eau, et, facultativement, au moins un monomère non fluoré très peu soluble dans l'eau, un composé organique macromoléculaire possédant une cavité hydrophobe; et b) la polymérisation de ce mélange de monomères.
