Abstract[English]
This invention discloses a poly (hexafluoropropylene oxide) (HFPO) mixture that contains a bifunctional and a monofunctional poly (HFPO) component. A process utilizing liquid or supercritical fluid chromatography may be used to separate the bifunctional from the monofunctional poly (HFPO) component. The bifunctional poly (HFPO) component that is separated is useful for coating the surface of an article wherein the coating may function as a lubricant for magnetic recording media, an anti-fingerprint coating for a touch screen display, or a coating for another article having a surface made of glass, metal, ceramic, or metal oxide.[French]
La présente invention concerne un mélange de poly (oxyde d'hexafluoropropylène) (HFPO) qui contient un composant poly(HFPO) bifonctionnel et monofonctionnel. Un procédé utilisant une chromatographie liquide ou supercritique peut être utilisé pour séparer le composant bifonctionnel du composant poly (HFPO) monofonctionnel. Le composant poly (HFPO) bifonctionnel qui est séparé est utile pour revêtir la surface d'un article, le revêtement pouvant faire office de lubrifiant pour des supports d'enregistrement magnétique, de revêtement anti-empreintes digitales pour un dispositif d'affichage à écran tactile, ou de revêtement pour un autre article ayant une surface constituée de verre, de métal, de céramique ou d'oxyde métallique.
