Abstract: To provide a method for producing a water/oil repellent composition, whereby an article which is excellent in the oil repellency while maintaining the water repellency and the heavy-rain durability, can be produced.A method for producing a water/oil repellent composition, which comprises mixing an emulsion of a polymer having from 10 to 50 mass % of units based on a monomer having a perfluoroalkyl group per all units and an emulsion of a monomer component containing at least 80 mass % of a monomer having a perfluoroalkyl group so that the proportion of the mass of the polymer will be from 50 to 99 mass % per the sum of the mass of the polymer and the total mass of the monomer component and then polymerizing the monomer component.

Abstract: A method for producing a water/oil repellent composition can produce an article which is excellent in the oil repellency while maintaining the water repellency and the heavy-rain durability. The method includes mixing an emulsion of a polymer having from 10 to 50 mass % of units based on a monomer having a perfluoroalkyl group per all units and an emulsion of a monomer component containing at least 80 mass % of a monomer having a perfluoroalkyl group so that the proportion of the mass of the polymer will be from 50 to 99 mass % per the sum of the mass of the polymer and the total mass of the monomer component and then polymerizing the monomer component. The monomer component includes emulsified particles in the emulsion of the monomer component. The emulsified particles have an average particle size of from 50 to 600 nm.

Abstract: To provide a water/oil repellent article which presents little burden on the environment, while being excellent in water/oil repellency, washing durability of the water repellency and friction durability of the water repellency; a method for producing such a water/oil repellent article; and a water/oil repellent composition and a water/oil repellent kit to be used for producing such a water/oil repellent article. A water/oil repellent article that comprises a substrate and, as adhered to the surface of the substrate, a fluorinated polymer having structural units based on monomer (a) having a C1-6 perfluoroalkyl group, and a specific fluorinated ether compound; a method for producing the water/oil repellent article, which comprises letting the fluorinated polymer and fluorinated ether compound be adhered to the substrate; a water/oil repellent composition which comprises the fluorinated polymer and fluorinated ether compound; and a water/oil repellent kit which comprises a first container accommodating a first liquid containing the fluorinated polymer and a second container accommodating a second liquid containing the fluorinated ether compound.
