WATER-REPELLANT/OIL-REPELLANT COMPOSITION, METHOD FOR PRODUCTION THEREOF, AND ARTICLE

摘要

Disclosed is a water-repellant/oil-repellant composition which can impart a water-repellant/oil-repellant property and has excellent durability (laundry durability and torrential rainfall durability). Also disclosed is a method for producing the composition. Further disclosed is an article which has a water-repellant/oil-repellant property and causes less decrease in the water-repellant/oil-repellant property by laundry or torrential rain. Specifically disclosed is a water-repellant/oil-repellant composition which comprises a copolymer having a polymerization unit derived from a monomer (a) and a polymerization unit derived from a monomer (b), wherein the ratio of the polymerization unit derived from the monomer (b) is 30 to 80 mol% relative to the total amount of the polymerization unit derived from the monomer (a) and the polymerization unit derived from the monomer (b): the monomer (a): a compound represented by the formula: (Z-Y)X[wherein Z represents a perfluoroalkyl group having 1 to 6 carbon atoms or the like; Y represents a bivalent organic group or the like; n represents a number of 1 or 2: and X represents a polymerizable unsaturated group]; and the monomer (b): a (meth)acrylate carrying no polyfluoroalkyl group and carrying an alkyl group having 20 to 30 carbon atoms.
