    摘要： A fluorine-containing copolymer, which is obtained by copolymerizing, as copolymer units, (A) the general formula:

            CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR=CH2

    wherein R is a hydrogen atom or a methyl group, n is 1 to 6, a is an integer of 1 to 4, b is 1 to 3, and c is 1 to 3; (B) the general formula: CH2=CRCOOR1 wherein R is a hydrogen atom or a methyl group, and R1 is a C1-C30 linear, branched, or cyclic hydrocarbon group that may contain an oxygen atom; (C) the general formula:

            CH2=CRCOO(H)p(R2Y)q

    wherein R is a hydrogen atom or a methyl group, p and q are 0 or 1, p + q is 1, R2 is a C1-C30 linear, branched, or cyclic divalent hydrocarbon group that may have an oxygen atom, and Y is a phosphate group; and (D) the general formula:

            CH2 =CRCOOR3 OCOCR=CH2

    wherein R is a hydrogen atom or a methyl group, R3 is a C1-C30 linear, branched, or cyclic divalent hydrocarbon group that may contain an oxygen atom,
    at a ratio of 1 to 50 wt.% of the component (B), 0.01 to 5 wt.% of the component (C) and 0.01 to 2 wt.% of the component (D). The fluorine-containing copolymer gives a substrate surface modied film having excellent water and oil repellency, rust resistance, and the like.
