ABSTRACT:
6-Hydroxyhexyl perfluoroisopropyl ether is prepared by reaction of hexafluoroacetone and potassium fluoride to obtain an alcoholate which is then reacted with 1-chloro-6-hexanol. One mole of the ether may be reacted with about 1 mole to about 20 moles of ethylene oxide. One mole of 2,2,3,4,4,4-hexafluorobutanol may also be reacted with about 1 mole to about 6 moles of propylene oxide and then about 1 mole to about 20 moles of ethylene oxide. Both ethoxylates are nonionic surfactants which are useful as antistatic agents and lubricants for polymeric shapes such as nylon films and filaments.
