Abstract: Polymers of the formula

IN WHICH Rf is perfluoroalkyl of six to 12 carbon atoms, n is an integer of 1 to 4, m is 0 or 1 and x is a number of about 10 to about 300, are useful as water- and oil-repellent agents for fibrous materials, especially materials consisting of or containing cotton or wool. The agents are used in aqueous dispersions or solutions in organic solvents.

Abstract translation: 其中R f为6至12个碳原子的全氟烷基，n为1至4的整数，m为0或1，x为约10至约300的数，可用作水和油 - 用于纤维材料的排斥剂，特别是由棉或羊毛组成或含有的材料。 这些试剂用于有机溶剂中的水性分散体或溶液中。

Abstract: 2-Perfluoroalkyl ethanols are obtained by reacting 2-perfluoroalkyl ethyliodides with at least the two-fold molar amount of nitric acid of about 70 to 98 percent strength and hydrogenating the intermediates, which are the nitrates of the desired ethanols. The products are useful as starting materials for the production of hydrophobic and oleophobic textile finishing agents, e.g. the polymer acrylates and methacrylates of said 2perfluoroalkyl-ethanols.

Abstract translation: 2-全氟烷基乙醇通过使2-全氟烷基乙基碘化物与至少两倍摩尔量的硝酸浓度为约70-98％的强度反应并氢化作为所需乙醇的硝酸盐的中间体来获得。 该产品可用作生产疏水和疏油纺织整理剂的起始材料，例如， 所述2-全氟烷基 - 乙醇的聚合物丙烯酸酯和甲基丙烯酸酯。
