Document Type and Number:
WIPO Patent Application WO/2021/054202
Kind Code:
A1
Abstract:
A fluorine-containing ether compound represented by formula (1). (1): R1-R2-CH2-R3-CH2-R4
(In the formula, R1 represents an organic group having an alicyclic structure and from 3 to 13 carbon atoms; R2 represents a group expressed by formula (2) (wherein a represents an integer from 1 to 3); R3 represents a perfluoropolyether chain; and R4 represents an end group which contains two or three polar groups that are bonded to different carbon atoms, with the carbon atoms to which the polar groups are bonded being bonded to each other via linking groups that contain carbon atoms to which polar groups are not bonded.)
