    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： This invention relates to chemical compositions comprising one or more urethane oligomers of at least two repeating units selected from the group consisting of fluorine-containing urethane oligomers and long-chain hydrocarbon-containing urethane oligomers. These urethane oligomers comprise the reaction product of (a) one or, more polyfunctional isocyanate compounds; (b) one or more polyols; (c) one or more monoalcohols selected from the group consisting of fluorochemical monoalcohols, optionally substituted long-chain hydrocarbon monoalcohols, and mixtures thereof; (d) one or more silanes; and optionally (e) one or more water-solubilizing compounds comprising one or more water-solubilizing groups and at least one isocyanate-reactive hydrogen containing group. The chemical compositions of the present invention can be applied as coatings and these coatings can impart stain-release characteristics and resist being worn-off due to wear and abrasion.
