FLUORINATED COPOLYMER, AND WATER- AND OIL-REPELLENT COMPRISING SAME AS ACTIVE INGREDIENT

摘要

Disclosed is a copolymer of a polyfluoroalkyl alcohol (meth)acrylic acid derivative represented by the formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR═CH2 (R: H or CH3, 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: R1(OR2)p(OR3)qOCOCR═CH2 (R: H or CH3; R1: H, an alkyl group, or an aromatic group; R2 and R3: 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.
