Abstract

Abstract New polyfluoroalkyl iodides of the formula ##EQU1## are provided, wherein R f represents a fluorinated hydrocarbon radical with 3 to 18 carbon atoms, R 1 represents hydrogen or fluorine, R 3 and R 4 each independently represents hydrogen, lower alkyl, hydroxyalkyl, carboxy, carbalkoxy, --(CH 2 ) p OCOR 2 , in which R 2 represents hydrogen or alkyl with 1 to 3 carbon atoms and p is 0 or a whole number from 1 to 3, phenyl and alkylphenyl, or R 3 and R 4 together with the carbon atoms to which they are bonded represent an optionally substituted cycloaliphatic radical with 5 or 6 ring carbon atoms, and n is a whole number from 1 to 3. The new compounds are useful as intermediates for the manufacture of oil- and water-repellents, as oil- and water-repellents per se, as lubricants and as surface active assistants.
