More Information
Summary:This fluorine-containing ether compound is represented by the following formula. R1-CH2-R2[-CH2-R3-CH2-R2]x-CH2-R4 (Where: R1 and R4 are terminal groups which include 2 or 3 polar groups, in which each polar group bonds to a different carbon atom, and in which carbon atoms to which the polar groups are bonded are bonded to each other via a linking group that includes a carbon atom to which a polar group is not bonded; x is 1-2; R2 is a perfluoropolyether chain; and R3 is formula (3-1) or (3-2).) L'invention concerne un composé éther fluoré représenté par la formule suivante. Ｒ１－ＣＨ２－Ｒ２［－ＣＨ２－Ｒ３－ＣＨ２－Ｒ２］ｘ－ＣＨ２－Ｒ４ (Dans la formule, Ｒ１ et Ｒ４ représentent des groupes terminaux qui contiennent deux ou trois groupes polaires, chaque groupe polaire étant lié à un atome de carbone différent, et ces atomes de carbone liés auxdits groupes polaires étant liés entre eux par l'intermédiaire d'un groupe de liaison contenant un atome de carbone non lié aux groupes polaires ; x vaut 1 à 2 ; Ｒ２ représente une chaîne perfluoropolyéther ; et Ｒ３ représente la formule （３－１） ou （３－２）. ) 下記式で表される含フッ素エーテル化合物。 Ｒ１－ＣＨ２－Ｒ２［－ＣＨ２－Ｒ３－ＣＨ２－Ｒ２］ｘ－ＣＨ２－Ｒ４（Ｒ１およびＲ４は、２つまたは３つの極性基を含み、各極性基がそれぞれ異なる炭素原子に結合し、前記極性基の結合している炭素原子同士が、極性基の結合していない炭素原子を含む連結基を介して結合している末端基；ｘは１～２；Ｒ２はパーフルオロポリエーテル鎖；Ｒ３は式（３－１）または（３－２）。）
