  It has been discovered by in present invention that, compared with a fluorosurfactant having only one betaine group per molecule, a fluorosurfactant having a plurality of betaine groups per molecule is superior in its ability to undergo electrostatic interaction with other components of a fire fighting composition thereby improving the performance of the fire fighting composition. Previously known fluorosurfactants comprise only one betaine group per molecule. In contrast, the present invention provides for a fluorobetaine copolymer containing a plurality of betaine groups.

  本发明发现，与每个分子只有一个甜菜碱基团的含氟表面活性剂相比，每个分子具有多个甜菜碱基团的含氟表面活性剂与灭火组合物的其他成分发生静电作用的能力更强，从而提高了灭火组合物的性能。以前已知的含氟表面活性剂每个分子只有一个甜菜碱基团。相比之下，本发明提供了一种含有多个甜菜碱基团的氟甜菜碱共聚物。

  Various fluoropolymers have been proposed for imparting oil and water repellency to leather. Commonly, these fluoropolymers are amphiphilic; i.e., they are made from at least one monomer which is hydrophobic and at least one monomer which is hydrophilic. The present invention identifies and remedies disadvantages associated with the ability of amphiphilic fluoropolymers to impart oil and water repellency to leather. Contrary to conventional thinking, it has now been discovered that the incorporation of hydrophilic groups in a fluoropolymer undesirably reduces its ability to impart water resistance to leather. Correspondingly, it has also been discovered that a fluoropolymer incorporating fewer or no hydrophilic groups imparts superior oil and water repellency to leather when compared to fluoropolymers incorporating more hydrophilic groups. Therefore, this invention provides fluoropolymers which incorporate reduced levels of hydrophilic groups.

  人们提出了各种含氟聚合物，用于赋予皮革拒油性和拒水性。通常，这些含氟聚合物都是两亲性的；也就是说，它们是由至少一种疏水性单体和至少一种亲水性单体制成的。本发明发现并解决了与两亲性含氟聚合物赋予皮革防油防水性能有关的缺点。与传统想法相反，现在人们发现，在含氟聚合物中加入亲水基团会降低其赋予皮革防水性的能力，这是不可取的。相应地，人们还发现，与含有较多亲水基团的含氟聚合物相比，含有较少亲水基团或不含亲水基团的含氟聚合物可赋予皮革优异的憎油性和憎水性。因此，本发明提供了含有较少亲水基团的含氟聚合物。
