摘要： A composition useful to provide oil repellency, water repellency, and stain resistance to substrates comprising a polymer prepared by contacting a polyfluoroalkyl sulfonyl halide with a compound of Formula II, III or IV (E-(O)q)3Si—O—(Si(R2)2—O)m—[Si(R3—NHR4)(R2)O]n—Si—((O)q-E)3 Formula II HR4N—R3—Si(R2)2—O—[Si(R2)2—O]m—[Si(R3—NHR4)(R2)O]n—Si(R2)2—R3—NHR4 Formula III HR4N—R3—Si(R2)2—O—[Si(R2)2—O]m—Si—((O)q-E)3 Formula IV wherein each R2 is independently a C1 to C8 alkyl, each R3 is independently a divalent group containing carbon, oxygen, and optionally at least one of nitrogen oxygen and sulfur, each R4 is independently H or C1 to C8 alkyl, each E is independently a C1 to C8 branched or linear alkyl, each q is independently zero or 1, m is a positive integer, and n is independently zero or a positive integer, such that n/(m+n) is zero or a positive fraction having a value up to about 0.7, and the polymer viscosity is less than or equal to 10000 mPa·s under a shear rate of 0.1 s−1 at a temperature of 20° C.
