Title (EN) FLUOROPOLYMER PRODUCED BY AQUEOUS POLYMERIZATION USING DISPERSED PARTICULATE OF FLUORINATED IONOMER
(FR) POLYMÈRE FLUORÉ OBTENU PAR POLYMÉRISATION AQUEUSE À L'AIDE DE PARTICULES DISPERSÉES D'IONOMÈRE FLUORÉ
Abstract:
(EN) A process for making an aqueous dispersion of fluoropolymer particles by providing dispersed particulate of fluorinated ionomer in an aqueous polymerization medium and polymerizing at least one fluorinated monomer in the aqueous polymerization medium in the presence of the dispersed particulate of fluorinated ionomer and initiator to form the aqueous dispersion of particles of fluoropolymer.
(FR) L'invention porte sur un procédé de fabrication d'une dispersion aqueuse de particules de polymère fluoré consistant à disposer des particules dispersées d'ionomère fluoré dans un milieu de polymérisation aqueux et à polymériser au moins un monomère fluoré dans le milieu de polymérisation aqueux en présence des particules dispersées d'ionomère fluoré et d'un initiateur pour former la dispersion aqueuse de particules de polymère fluoré.
