Abstract

Provided is a fluorine-containing polymer that has water repellency and photosensitivity equivalent to those of conventional fluorine-containing polymers but can be decomposed at a lower temperature. A fluorine-containing polymer of the present disclosure contains a repeating unit represented by the following formula (1) or (1)', wherein, in formula (1), R<1> is a hydrogen atom, a fluorine atom, a chlorine atom, or a C1-C10 linear or C3-C10 branched alkyl group, some or all of the hydrogen atoms bonded to the carbon atoms in the alkyl group being optionally replaced by fluorine atoms; in formula (1), R<2> is a single bond, an alkylene group optionally having a linear, branched, or cyclic structure, an aromatic ring, an ester, a carbonyl, an ether, an amide, an amine, or a composite substituent thereof, a part of which is optionally fluorinated and/or chlorinated; in formula (1)', R<1a> is a C1-C10 linear or C3-C10 branched alkyl group, some or all of the hydrogen atoms bonded to the carbon atoms in the alkyl group being optionally replaced by fluorine atoms and/or chlorine atoms; in formula (1)', R<2a> is an alkylene group optionally having a linear, branched, or cyclic structure, an aromatic ring, an ester, a carbonyl, an ether, an amide, an amine, or a composite substituent thereof, a part of which is optionally fluorinated and/or chlorinated; in formula (1)', R<2b> is an alkylene group optionally having a linear, branched, or cyclic structure, an aromatic ring, an ester, a carbonyl, an ether, an amide, an amine, or a composite substituent thereof, a part of which is optionally fluorinated and/or chlorinated; in formulae (1) and (1)', X is a hydroxy group, an alkoxy group, an oxycarbonyl group, an oxysulfonyl group, an oxycarboxy group, or a hydrogen atom; and in formulae (1) and (1)', n is a natural number of 1 to 3. <img class="EMIRef" id="3728fb99-077b-4095-85a5-b6dc449f3527-ia01" />
