Abstract
New compositions having the following general formula: ##STR1## in which A. C.sub.n F.sub.2n+1 represents a straight or branched perfluorinated chain with n being 1 and 20. B. X.sup.- is an anion such as a halogen, a sulfate, an alkyl sulfate. Of these anions the preferred ones are halogens such as the fluoride, chloride, bromide and iodide, or sulfates such as EQU CH.sub.3 SO.sub.4.sup.-, c. R', R" and R'" correspond to the following definitions: 1. R' is an alkyl radical containing from 1 to 8 atoms of carbons, in which event PA1 I. R" and R'" can be either the same as R' or different, namely, alkyl radicals containing from 1 to 8 atoms of carbon. R" and R'" can also be cycloalkyl radicals containing from 5 to 10 carbon atoms or alkenyl radicals containing from about 3 to 8 atoms of carbon, or cycloalkenyl radicals containing from 5 to 9 atoms of carbon, or ayrl radicals. PA1 Ii. R" and R'" together make up a divalent radical linked to the nitrogen by two simple bonds such as cycloalkyl radicals containing from 4 to 9 carbon atoms, cycloalkenyl radicals containing 4 to 9 carbons, or cyclodienic radicals containing from 4 to 9 carbons. 2. R', R" and R'" make up together the remain…
