Abstract
Abstract This invention relates to carboxylated polyfluoroamine compounds of the general formula ##STR1## wherein the radical C n F 2n +1 -- is a straight or branched perfluorinated chain, n is an integer from 1 to 20, a is an integer from 2 to 10, p is an integer from 1 to 10, R 2 and R 3 each is an alkyl radical containing from 1 to 6 carbon atoms and R 1 is a hydrogen atom or an alkyl radical containing from 1 to 6 carbon atoms and the process for their preparation.
