A solution type water-and-oil repellant composition comprising: a graft copolymer having repeating units derived from a vinyl monomer having a perfluoroalkyl group and repeating units derived from a polymerizable cyclic acid anhydride; and an organic solvent. The composition has high product stability, is highly stable to dilution, and can impart high water and oil repellency.
L'invention concerne une composition hydrofuge et oléofuge de type solution, composée d'un copolymère greffé ayant des unités récurrentes dérivé d'un monomère vinylique ayant un groupe perfluoroalkyle et des unités récurrentes dérivé d'un anhydride d'acide cyclique polymérisable, et d'un solvant organique. Ladite composition présente une grande stabilité de produit, est très stable par rapport à la dilution, et peut conférer des propriétés hydrofuges et oléofuges élevées.
