Zusammenfassung:	A process for producing flowable and liquid dispersable particles of a highly fluorinated ion exchange polymer is provided in which a dispersion of a highly fluorinated ion exchange polymer in a liquid comprised of at least 10 wt% of an organic liquid is provided, atomized to produce droplets, and released into a inert heated gas. The dispersion droplets dry to produce flowable particles of highly fluorinated ion exchange polymer having dry exterior surfaces and an internal residual moisture content of at least 4 wt%. Procédé d'obtention de particules fluides et liquides dispersables d'un polymère à échange ionique hautement fluoré selon lequel une dispersion dudit polymère dans un liquide constitué pour au moins 10% d'un liquide organique est atomisée sous forme de gouttelettes et libérée dans un gaz inerte chauffé. Au séchage, les gouttes de dispersion produisent des particules fluides d'un polymère à échange ionique hautement fluoré présentant des surfaces extérieures sèches et une teneur en eau résiduelle interne d'au moins 4 % en poids.
