Abstract
The invention is directed to fluorinated compounds of the formula ##STR1## wherein R.sub.f is a perfluoroalkyl or perfluoroalkoxy-perfluoroalkyl group, R.sup.1 is a branched or straight chain alkylene, alkylenethioalkylene, alkyleneoxyalkylene or alkyleneiminoalkylene group, X is oxygen or an amino group, Q is an organic group containing at least one amino group and y is zero or 1, and the corresponding succinimides. These compounds are useful as surfactants.
Claims13
A compound of the formula ##STR71## or its amphoteric tautomer or of the formula ##STR72## or its amphoteric tautomer or a mixture thereof wherein R.sub.f is straight or branched chain perfluoroalkyl of 1 to 18 carbon atoms or said perfluoroalkyl substituted by perfluoroalkoxy of 2 to 6 carbon atoms;
- R.sup.1 is branched or straight chain alkylene of 1 to 12 carbon atoms;
- Y is 1 or zero;
- R is hydrogen, alkyl of 1 to 6 carbon atoms or hydroxyalkyl of 1 to 6 carbon atoms, and
- Q is an aliphatic amino group of the formula ##STR73## wherein R.sup.2 is a linear or branched alkylene of 2 to 12 carbon atoms;
- k is 1 or zero;
- R.sup.3 and R.sup.4 are independently of each other hydrogen, alkyl of 1 to 20 carbon atoms or said alkyl substituted by an alkyl group of 1 to 5 carbons.
