Abstract | Provided is a fluorine-containing ether compound represented by the following formula. R1-CH2-R2-CH2-R3-CH2-R4-CH2-R5-CH2-R6-CH2-R7 (R2, R4, and R6 are perfluoropolyether chains having the same structure; R3 and R5 are each independently a connecting group including one or more hydroxyl groups; and R1 and R7 are each independently formula (2).) -O-CH2-CH(OH)-([D]-CH(OH)s-[E]-CH2OH (2) (s is 0 or 1; [D] and [E] are each independently a chain-like structure constituted of a combination of 2-5 methylene groups and one oxygen atom or a chain-like structure constituted of 1-4 methylene groups, with the proviso that, when s is 0 and [E] includes an oxygen atom, the number of methylene groups included in [E] is 3 or more.)
L'invention concerne un composé éther contenant du fluor représenté par la formule suivante. R1-CH2-R2-CH2-R3-CH2-R4-CH2-R5-CH2-R6-CH2-R7 (R2, R4 et R6 représentent des chaînes de perfluoropolyéther ayant la même structure ; R3 et R5 représentent chacun indépendamment un groupe de liaison comprenant un ou plusieurs groupes hydroxyle ; et R1 et R7 sont chacun indépendamment de formule (2).) -O-CH2-CH(OH)-([D]-CH(OH)s-[E]-CH2OH (2) (s est 0 ou 1 ; [D] et [E] sont chacun indépendamment une structure de type chaîne constituée d'une combinaison de 2 à 5 groupes méthylène et d'un atome d'oxygène ou d'une structure de type chaîne constituée de 1 à 4 groupes méthylène, à condition que, lorsque s vaut 0 et [E] comprend un atome d'oxygène, le nombre de groupes méthylène inclus dans [E] est supérieur ou égal à 3.)
