Provided are: uses of a polymer that includes structural units derived from compounds represented by formula (a), as a surfactant having a superior ability to reduce surface tension or as a surface modifier and coating material for imparting antifouling properties; and a composition in each of these uses. Further provided is a novel fluorine-containing compound which is useful as a surfactant from among the aforesaid compounds. CH2=CR1-COX-CR2R3-(CH2)n-COO-Q1-Rf1 (a) In the formula, X is -0- or -NR4-; R1 is a hydrogen atom or methyl group; R2, R3, and R4 are each independently a hydrogen atom, a C1-3 alkyl group, or a group represented by formula (r) -(CH2)m-COO-Q2-Rf2 (r); n and m are each independently an integer 0-4; Rf1 and Rf2 are each independently a C1-6 polyfluoroalkyl group or polyfluoroether group; and Q1 and Q2 are each independently a single bond or divalent linking group. |
