(57) [PROBLEMS] To provide a novel fluorine-containing compound, a fluorine-containing polymer excellent in solubility in a solvent, and a water- and oil-repellent composition excellent in water and oil repellency with little environmental load. Provided. ZCH 2 CF (CF 3 ) [OCF 2 CF (CF 3 )] n OR f (Z is HO— or CH 2 ═CR 1 COO-. R 1 is a hydrogen atom or a methyl group. R f is a polyfluoroalkyl group having 4 to 20 carbon atoms. n is 0-10 Integer. ), A fluorine-containing polymer obtained by polymerizing the compound, and a water / oil repellent composition containing the polymer. |
