WATER AND OIL REPELLENT COMPOSITION AND PROCESS FOR ITS PRODUCTION

摘要

A water-and-oil repellant composition of the aqueous dispersion type which c an impart highly long-lasting water-and-oil repellency to fibers of various materials. The composition comprises: a polymer comprising as essential unit s a polymer unit derived from a (meth)acrylate having a polyfluoroalkyl group and a polymer unit derived from a polymerizable monomer which essentially contains a polymerizable unsaturated group and a hydroxyl group and in which these groups are connected to each other through seven or more covalent bond s; a surfactant comprising 60 to 100 wt.% nonionic surfactant; an aqueous mediu m; and a crosslinking compound.
