Abstract:
1. A process for producing a water- and oil-repellent agent, which process comprises subjecting (a) 15-85% by weight of polyfluoroalkylethyl acrylate, (b-1) 5-65% by weight of 2-ethylhexyl methacrylate, and (b-2) 1-40% by weight of benzyl methacrylate to an emulsification treatment in the presence of (c) a polyethylene oxide adduct type, cationic surfactant, or both of the cationic surfactant and a polyethylene oxide adduct type, non-ionic surfactant, and (d) a glycol-based compound, followed by copolymerization reaction in the presence of a polymerization initiator, and admixing the resulting aqueous dispersion with (e) a blocked isocyanate.
