Aqueous dispersion of water- and oil-repellent and process for the production thereof |
摘要 |
Provided is an aqueous water- and oil-repellent dispersion free of an organic solvent and having durable water- and oil-repellency and excellent storage stability. The aqueous water- and oil-repellent dispersion is produced by emulsifying a perfluoroalkyl group-containing (meth)acrylate copolymer with the use of an ionic surfactant and/or a nonionic surfactant having less than 8 mol of added ethylene oxide per one hydrophobic group so that an average particle diameter is at most 100 nm and an integrating sphere turbidity is at most 20 (kaolin); adding, before the polymerization, a surfactant having at least 8 mol of added ethylene oxide per one hydrophobic group and a protective colloid; and conducting the polymerization.
