摘要：
A surfactant comprising a graft polymer having a branch polymer and a trunk polymer, at least one of which contains a fluoroalkyl group, has high solubility in a liquid medium and shows a superior surface tension-lowering action, in spite of containing fluoroalkyl groups at a high concentration. The surfactant also has high solubility in a liquid medium, in spite of containing a short-chain perfluoroalkyl group which is poor in surface tension-lowering action, and further shows a superior action to decrease the surface tension of a solution. The use of this surfactant can provide a liquid dispersion well dispersed in a liquid medium having a small environmental load.
