Abstract

Procédé de purification de fluoropolymères selon lequel on met en contact ces derniers avec un cycloalcane perfluoré liquide à des températures supérieures à 140 °C. Les polymères résultants sont tout particulièrement utiles dans les cas où l'on recherche des polymères renfermant peu d'impuretés tels que dans des dispositifs médicaux et dans des éléments destinés à l'industrie de fabrication des semi-conducteurs. Les cycloalcanes perfluorés liquides améliorent l'adhérence des fluoropolymères entre eux et sur d'autres matériaux.
