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

摘要

Disclosed is a method for producing a water-repellant/oil-repellant composition which can impart a water-repellant/oil-repellant property to the surface of an article and has excellent durability (laundry durability and torrential rainfall durability). Also disclosed is an article which has a water-repellant/oil-repellant property and is hardly decreased in its water-repellant/oil-repellant property when undergoes laundry or torrential rain. Specifically disclosed is a method for producing a water-repellant/oil-repellant composition, which comprises polymerizing a monomer component comprising a monomer (a) in a solvent in the co-presence of a compound (x) in the presence of a surfactant and a polymerization initiator, wherein the monomer (a) is a compound represented by the formula (Z-Y)X [wherein Z represents a polyfluoroalkyl group having 1 to 20 carbon atoms or the like; Y represents a bivalent organic group or a single bond; n represents a number of 1 or 2; and X represents a polymerizable unsaturated group] and the compound (x) is a compound having at least two groups each represented by the formula-(CH)-CHR-(CH)-SH [wherein Rrepresents a methyl or ethyl group; a represents an integer of 0 to 2; and b represents a number of 0 or 1].
