(57) [Summary] (Modified) [Constitution] Di-, tri- and poly-formulas of general formula I or II Methods of making perfluoroalkyl-substituted alcohols and acids and their derivatives from perfluoroalkyl iodides and di-, tri- or poly-allyl alcohols or acids are provided. These compounds have one or more perfluoroalkyl-iodoalkyl groups or perfluoroalkyl-alkylene groups and one or two alcohol or acid groups or derivatized alcohol or acid functional groups. (I) (Q F -CH 2 O) b -Y- (X) a, (II) Z e (-L- (U-OH) d ) c Specific examples of the present alcohol include the following: 1-butanol, 2,2-bis (((4,4,5,5,6,6,6, 7, 7, 8, 8, 9, 9, 10, 10, 11, 11, 1 1-Heptadecafluoro-2-undecenyl) oxy) Methyl) [Effect] These compounds react with isocyanates, epoxy compounds, acid anhydrides or acid derivatives to provide various oil-repellent and water-repellent compounds. These are knitted fabrics, It is useful for oil and water repellency treatment of substrates such as glass, paper and leather. |
