Abstract
A fluorocopolymer formed from, as essential ingredients, (a) a fluoromonomer represented by the general formula: CH2═C(—X)—C(—O)—Y—[—(CH2)m-Z-]p-(CH2)n—Rf (1) [wherein X is hydrogen, C1-21 linear or branched alkyl, fluorine, chlorine, bromine, iodine, —CFX1X2 (wherein X1 and X2 each is hydrogen, fluorine, chlorine, bromine, or iodine), cyano, C1-21 linear or branched fluoroalkyl, (un)substituted benzyl, or (un)substituted phenyl; Y is —O— or —NH—; Z is —S— or —SO2—; Rf is C1-21 fluoroalkyl; m is 1-10; n is 0-10; and p is 0 or 1] and (b) a polyalkylene glycol (meth)acrylate. A soil remover containing this fluorocopolymer imparts to a woven fabric, etc. excellent oil repellency, unsusceptibility to fouling, and the property of releasing stains therefrom, while maintaining durability in washing.
