    摘要： A method of making a fluoropolymer dispersion by first providing a fluoropolymer dispersion comprising fluoropolymer particles and one or more fluorinated surfactants selected from fluorinated carboxylic acids or salts thereof having the general formula: [Rf—O-L-COO−]iXi+  (I) wherein L represents a linear partially or fully fluorinated alkylene group or an aliphatic hydrocarbon group, Rf represents a linear partially or fully fluorinated aliphatic group or a linear partially or fully fluorinated aliphatic group interrupted with one or more oxygen atoms, Xi+ represents a cation having the valence i and i is 1, 2 or 3; Then adding one or more non-fluorinated surfactants selected from anionic and non-ionic surfactants followed by reducing the total amount of the one or more fluorinated surfactants to an amount of not more than 500 ppm, for example not more than 250 ppm based on the total weight of the dispersion while maintaining or increasing the amount of solids in the dispersion.

    摘要： A composition including at least one first divalent unit represented by formula: Each Rf is independently selected from the group consisting of Rfa—(O)t—CHF—(CF2)n—; [Rfa—(O)t—C(L)H—CF2—O]m—W—; Rfb-O—(CF2)p-; F(CkF2k)—(O—CkF2k)P—O—CF2—; and CF3—O—(CF2)3—(OCF(CF3)—CF2)Z—O-L1-. Each Q is independently selected from the group consisting of a bond, —C(O)—N(R1)—, and —C(O)—O—. Each X is independently selected from the group consisting of alkylene and arylalkylene, wherein alkylene and arylalkylene are each optionally interrupted by at least one ether linkage and optionally terminated by —N(R1)—C(O)— or —O—C(O)—. R and R1 are each independently selected from the group consisting of hydrogen and alkyl having from 1 to 4 carbon atoms. Rfa represents a partially or fully fluorinated alkyl group having from 1 to 10 carbon atoms and optionally interrupted with at least one oxygen atom. Rfb is selected from the group consisting of CF3CFH— and F(CjF2j)-. Methods of reducing surface tension of a liquid, making foams, and treating a surface using the compositions are also disclosed.
