Abstract

La présente invention concerne une composition contenant du fluor comprenant un polymère contenant du fluor comportant un motif répété issu d'un monomère contenant du fluor représenté par la formule (a) : CH2=C(-X)-C(=O)-Y-Z-W-Rf (dans cette formule, X représente un atome d'hydrogène, un groupe organique monovalent ou un atome d'halogène ; Y représente -O- ou -NH- ; Z représente une liaison directe ou un groupe organique divalent ; Rf représente un groupe fluoroalkyle comportant de 1 à 20 atomes de carbone ; et W représente -(CL1L2-CL3L4)a- ou -(CL5L6-CL7L8)a- (au moins l'un des L1 à L4 représentant un atome de chlore ; au moins l'un des autres L1 à L4 représentant un atome d'hydrogène ; au moins l'un des L5 à L8 représentant un groupe hydrocarbure comportant de 1 à 22 atomes de carbone ; au moins l'un des autres L5 à L8 représentant un atome de fluor ; et a représentant un nombre entier de 1 à 50)). Même dans le cas où le composé contenant du fluor utilisé en tant que monomère contenant du fluor correspond à un groupe perfluoroalkyle ne comportant pas plus de 6 atomes de carbone, il se révèle suffisant pour conférer les propriétés requises d'un agent hydrofuge/oléofuge, d'un agent antisalissures ou d'un agent de démoulage.
