The present invention is directed to 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, giving a solvent-based water- and oil-repellent composition having high water- and oil-repellency, high product stability and high dilution stability.
L'invention concerne un polymère greffé composé d'un polymère squelette et d'un polymère ramifié contenant fluoroalkyle greffé sur le polymère squelette par une liaison comprenant -C(=O)NH-. Ce polymère greffé peut donner des compositions hydrofuges et oléofuges solubles possédant un grand pouvoir hydrofuge et oléofuge et présentant une grande stabilité du produit et une grande stabilité de dilution.
