## Abstract

A fluorine-containing copolymer that is a copolymer of: a polyfluoroalkyl alcohol (meth)acrylate represented by the general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR═CH2 [I] (R: a hydrogen atom, a methyl group, n: 1 to 6, a: 1 to 4, b: 1 to 3, and c: 1 to 3); benzyl (meth)acrylate or styrene; and a Si group-containing crosslinkable (meth)acrylate represented by the general formula: CH2═CRCOO(CH2)dSi(OR1)eR23-e [II] (R: a hydrogen atom, a methyl group, R1, R2: an alkyl group having 1 to 10 carbon atoms, d: 1 to 3, e: 1 to 3). The surface-modifying agent comprising this fluorine-containing copolymer as an active ingredient have an excellent dynamic slip angle after washing with hexadecane, and anti-corrosive properties.
