    摘要： A method of providing water repellency, alcohol repellency, oil repellency, and soil resistance to substrates comprising contacting said substrate with a composition comprising a copolymer having repeating units of Formula 1 in any sequence: [Rf(CH2)kOC(O)NH(CH2)kOC(O)C(T)CH2]m—[Wq]p—Formula 1 wherein Rf is a straight or branched perfluoroalkyl group having from about 2 to about 8 carbon atoms, or a mixture thereof, which is optionally interrupted by at least one oxygen atom, each k is independently a positive integer from 1 to about 6, T is hydrogen or methyl, m is a positive integer, q is zero or a positive integer, p is zero or a positive integer, and W is or or —[R1—X—Y—C(O)—CZ-CH2]—, wherein X is an organic divalent linking group having from about 1 to about 20 carbon atoms, optionally containing a triazole, oxygen, nitrogen, or sulfur, or a combination thereof, Y is O or N(R) wherein R is H or C1 to C20 alkyl, Z is H, a straight or branched alkyl group having from about 1 to about 4 carbon atoms, or halide, Rx is C(O)O(R1), C(O)N(R2)2, OC(O)(R1), SO2(R1), C6(R3)gH(5-g), O(R1), halide, or R1; each R1 is independently H, CnH2n+1, CnH2n—CH(O)CH2, [CH2CH2O]iR4, [CnC2n]N(R4)2 or [CnH2n]CnF2n+1, n is 1 to about 40, R4 is H or CsH2s+1, s=0 to about 40, i=1 to about 200, each R2 is independently H, or CtH2t+1 wherein t is 1 to 20, each R3 is independently R4, COOR1, halogen, N(R1)2, OR1, SO2NHR1, CH═CH2, or SO3M, g is 1 to 5, and M is H, alkali metal salt, alkaline earth metal salt, or ammonium.
