Compared with conventional hydroxyl-terminated polyethers, the fluorine-containing polyether polyols can be used to prepare polymers with better performances, such as water repellent and oil repellent, self-cleaning, self-lubricating, and resistant to heat, UV light, weathering, corrosion, chemical, solvent and so on. Therefore it has a wide range of potential applications and development prospects. In this article, preparation technical approaches and chemical structure features of fluorine-containing polyether polyols at home and abroad have been reviewed in detail. Research progresses on fluorine-containing polyether polyol used in polyurethane elastmers, coatings and other application areas are briefly introduced. It is pointed out that the main directions of fluorine-containing polyether polyols for the future research and development should focus on lowering products costs, developing green high performance technical process, simplifying preparation techniques, optimizing the process conditions, and developing new products.
