These compounds contain two or more perfluoroalkyl-iodoalkyl or perfluoroalkyl-alkenyl groups and one or two alcohol or acid groups or derivatized alcohol or acid functions. They can be reacted with isocyanates, epoxy compounds, anhydrides, acids or acid derivatives to prepare a great variety of oil- and water-repellent compositions which are useful for oil- and water-repellent treatment of textiles, glass, paper, leather and other substrates.Other References
