Abstract
New perfluorinated amino compounds of the formula ##EQU1## ARE PROVIDED WHEREIN R.sub.f represents a perfluorinated hydrocarbon radical with 1 to 18 carbon atoms and R represents hydrogen or methyl each of R.sub.1, R.sub.2 and R.sub.3 independently represents hydrogen or the radical ##EQU2## in which R.sub.f and R have the meanings already assigned to them, p is an integer from 2 to 6 and m is an integer from 1 to about 500. Due to their surface-active properties the new compounds are useful e.g as foaming, wetting and levelling agents or as emulsifiers. They can be further used as soil-repellent additives for polishes and waxes, as corrosion inhibitors in oils or lubricants and they are also useful as intermediates for the manufacture of oil and water repellents.
