  • Fluorine-containing copolymer and surface-modifying agent comprising the same as active ingredient
    Patent number: 10344172
    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.

  • FLUORINE-CONTAINING POLYMER AND SURFACE-MODIFYING AGENT CONTAINING THE SAME AS ACTIVE INGREDIENT
    Publication number: 20160251468
    Abstract: A fluorine-containing copolymer comprising a copolymer of (A) CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR?CH2 (R:H, a methyl group, n:1-6, a:1-4, b:1-3, c:1-3), (B) CH2?CRCOOR1(R:H, a methyl group, R1:C1-C30 alkyl group, or an aralkyl group; and (C) CH2?CRCOOR2NCO or CH2?CRCOOR2NHCOR3 (R:H, a methyl group, R2:C1-C30 alkylene group, R3 :blocked group of an isocyanate group, and a surface-modifying agent containing the fluorine-containing copolymer as an active ingredient. The surface-modifying agent has excellent adhesion to substrates and improved processing durability.
