Disclosed is a fluorine-containing copolymer comprising a copolymer of a polyfluoroalkyl alcohol (meth)acrylic acid derivative represented by the general formula:
CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR=CH2
wherein R is a hydrogen atom or a methyl group, n is an integer of 1 to 6, a is an integer of 1 to 4, b is an integer of 1 to 3, and c is an integer of 1 to 3, and styrene or a derivative thereof; and also disclosed is a surface modifier comprising the fluorine-containing copolymer as an active ingredient. When the fluorine-containing copolymer is used as an active ingredient of a surface modifier, the heat resistance of the surface modifier can be further improved.
