Abstract

L'invention a pour objet des fibrilles en polymères fluorés, obtenues par introduction de la solution d'un polymère dans un milieu precipitant liquide se trouvant dans un champ de cisaillement Selon l'invention, on utilise des polymères ou copolymères fluorés de chlorure de vinyle ou de vinylidène.
