Document Type and Number:
WIPO Patent Application WO/2023/224093
Kind Code:
A1
Abstract:
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).)
