Abstract
New fluorinated carboxylic acid amides of the formula ##STR1## are provided wherein R.sub.f is a perfluoroalkyl radical with 1 to 18 carbon atoms, R is hydrogen or methyl, R.sub.1 is hydrogen or R.sub.f CHOHCHR--, if m is 1, and hydrogen, alkyl with 1 to 18 carbon atoms, cycloalkyl with 5 or 6 carbon atoms, hydroxyalkyl with 2 to 6 carbon atoms, alkoxyalkyl with 1 to 4 carbon atoms in the alkoxy moiety or R.sub.f CHOHCHR--, if m is 0, A is an ethylenically unsaturated hydrocarbon radical with 2 or 3 carbon atoms, m is 0 or 1, y is 1 or 2 and p is an integer from 2 to 6. The fluorinated carboxylic acid amides are useful e.g. as wetting agents, emulsifiers or dispersants and for producing oil-repellent finishes on porous or nonporous substrates or as intermediates for the manufacture of homo- or copolymers, which show also oil-repellent properties.
