Title: Anionic fluorochemical surfactants

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 to produce a hydroxyethyl ether. One mole of 2,2,3,4,4,4-hexafluorobutanol may be reacted with from about 1 to about 5 moles of propylene oxide to produce a hydroxypropyl ether. One mole of hexafluorobutanol may also be reacted with about 1 to about 5 moles of propylene oxide and then about 1 mole to about 20 moles of ethylene oxide to produce a hydroxyethyl ether. The hydroxyhexyl ether, hydroxylpropyl ether and both hydroxyethyl ethers may be sulfated to produce anionic surfactants which are useful as antistatic agents and lubricants for polymeric shapes such as nylon films and filaments.
