Title (EN) FLUOROPOLYMER, PROCESS FOR PREPARING THE SAME, AND USE THEREOF
(FR) POLYMERE FLUORE, SON PROCEDE DE PREPARATION ET SON UTILISATION
Abstract:
(EN) A fluoropolymer having a number average molecular weight of 500 to 100000 and represented by the general formula Rf-(OC3F6)a -(OC2F4 )b -(OCF2)c-X-Y-Z-MPnRm-n RnRm-nM-Z-Y-X-(OC3F6)a -(OC2F4)b -(OCF2)c -X-Y-Z-MPnRm-n (wherein Rf represents a perfluoroalkyl group; a, b, and c each independently represents 0, 1 or above, provided that the sum of a, b, and c is at least 1; X represents a group represented by the general formula: -(O)d-(CF2)e -(CH2)f-; Y represents a divalent polar group; Z represents a group represented by the formula: -(CH2)g-; M represents a metal atom; R represents a hydrocarbon group; P represents a hydrolyzable polar group; m represents an integer of (valency of M - 1); and n is an integer of 1 to m). The polymer can form on a substrate an antifouling layer excellent in the antifouling effect on an oleaginous contaminant, particularly on fingerprints.
(FR) Polymère fluoré possédant un poids moléculaire moyen en nombre de 500 à 100000 et représenté par la formule générale Rf-(OC3F6)a -(OC2F4 )b -(OCF2)c-X-Y-Z-MPnRm-n RnRm-nM-Z-Y-X-(OC3F6)a -(OC2F4)b -(OCF2)c -X-Y-Z-MPnRm-n (dans laquelle Rf représente un groupe perfluoroalkyle; a, b et c sont chacun indépendamment égaux ou supérieurs à 0 ou 1, à condition que la somme de a, b et c soit au moins 1; X représente un groupe représenté par la formule: -(O)d-(CF2)e -(CH2)f-; Y représente un groupe polaire divalent; Z représente un groupe représenté par la formule: -(CH2)g-; M représente un atome de métal; R représente un groupe hydrocarbure; P représente un groupe polaire hydrolysable; m est un entier de valence de M-1; et n est un entier de 1 à m). Ce polymère peut constituer sur un substrat une couche antisalissure particulièrement appropriée contre des contaminants oléagineux, en particulier, les empreintes de doigts.
