Abstract
A fluorine-containing polymer includes a repeating unit represented by General Formula (I). In General Formula (I), L1 represents a single bond or a divalent linking group, R1 represents a hydrogen atom, a fluorine atom, a chlorine atom, or an alkyl group having 1 to 20 carbon atoms, and R2 represents a group including a fluorine atom
Claims19
A fluorine-containing polymer comprising a repeating unit represented by General Formula (I),
- in General Formula (I), L1 represents a single bond or a divalent linking group, R1 represents a hydrogen atom, a fluorine atom, a chlorine atom, or an alkyl group having 1 to 20 carbon atoms, and R2 is a group including at least one of:
- (a) a group represented by Formula (1), (2), or (3),
- (b) a perfluoropolyether group, or
- (c) an alkyl group having 1 to 20 carbon atoms, in which the alkyl group has a hydrogen bond between a proton-donating functional group and a proton-accepting functional group, and at least one carbon atom has a fluorine atom as a substituent,
