    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.

    摘要: A method of making a fluoropolyether elastomer containing triazine groups and having a glass transition temperature of less than -40 °C, including providing (i) one or more saturated fluoropolyethers containing repeating moieties selected from (-C
    4 F
    8 O-), (-C
    3 F
    6 O-), (-C
    2 F
    4 O-), (-CF
    2 O-) and combinations thereof and further containing at least one functional group at a terminal carbon atom of the backbone chain, or of a side chain if present, wherein the terminal carbon atom may be a primary or secondary carbon atom and wherein the functional group is capable of reacting with a functional group of the fluorinated compound according to (ii) below to form a triazine ring, (ii) one or more fluorinated compound containing at least one perfluorinated alkyl or perfluorinated alkylene moiety wherein the carbon atoms of the perfluorinated alkyl or alkylene moiety may be interrupted by one or more oxygen atoms and wherein the fluorinated compound further contains at least one functional group capable of reacting with the functional group of the one or more fluoropolyethers to form a triazine; curing the components according to (i) and (ii) to form triazines. Further provided are cured compositions, articles comprising the cured compositions and methods of making articles.
