摘要:
A graft polymer, which is obtained by grafting a branch polymer having a fluoroalkyl group onto a trunk polymer through a linkage having a —C(═O)NH— group, gives a solvent-based water- and oil-repellent composition having high water- and oil-repellency, high product stability and high dilution stability.
