    摘要： The present invention relates to compositions based on a fluoropolymer comprising repeating units derived from (i) one or more fluorinated monomers selected from the group consisting of monomers according to the general formula: Rf—X—OC(O)—C(R)═CH2 wherein Rf represents a perfluorinated aliphatic group having 3 or 4 carbon atoms, X is an organic divalent linking group and R represents hydrogen or a lower alkyl group having 1 to 4 carbon atoms; and (ii) one or more non-fluorinated comonomers. The fluoropolymer has a weight average molecular weight between 3000 and 55000. The compositions may be solvent born or aqueous born and are particularly useful to provide good oil- and/or water repellency properties to the substrate.

    摘要翻译： 本发明涉及基于含氟聚合物的组合物，其包含衍生自（i）一种或多种氟化单体的重复单元，所述氟化单体选自根据以下通式的单体：Rf-X-OC（O）-C（R）= CH2，其中Rf表示具有3或4个碳原子的全氟化脂族基团，X是有机二价连接基团，R表示氢或具有1至4个碳原子的低级烷基; 和（ii）一种或多种非氟化共聚单体。 所述含氟聚合物的重均分子量为3000至55000。所述组合物可以是溶剂型的或出生的水溶液，并且特别可用于向基材提供良好的油和/或拒水性。
