<p>Disclosed is a copolymer of a polyfluoroalkyl alcohol (meth)acrylic acid derivative represented by the formula: C n F 2n+1 (CH 2 CF 2 ) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c OCOCR=CH 2 (R: H or CH 3 , n: 1 to 6, a: 1 to 4, b: 1 to 3, and c: 1 to 3), and a (meth)acrylic acid polyoxyalkylene ester represented by the formula: R 1 (OR 2 ) p (OR 3 ) q OCOCR=CH 2 (R: H or CH 3 ; R 1 : H, an alkyl group, or an aromatic group; R 2 and R 3 : alkylene groups having 1 to 6 carbon atoms; p: 2 to 50, q: 0 or 1 to 50), and also disclosed is a water- and oil-repellent comprising this fluorine-containing copolymer as an active ingredient. The water- and oil-repellent comprising this fluorine-containing copolymer as an active ingredient can be used as a stain-proof-type water- and oil-repellent that can apply effective stain-proof finish and stain removal finish to fiber fabrics, and that has excellent washing durability.</p> |
