ABSTRACT:
This invention relates to compounds which simultaneously contain a perfluorinated chain and a hydrogenated chain and which correspond to the general formula: ##STR1## in which R.sub.F is a perfluoroalkyl radical, m an integer from 0 to 2, R.sub.H an alkyl radical, X an OH or NR.sub.1 R.sub.2 group, and R.sub.1 and R.sub.2 are hydrogen atoms or methyl radicals. The amides (X=NR.sub.1 R.sub.2) are prepared by photoamidation of the polyfluoroolefins R.sub.F --(CH.sub.2).sub.p --CH.dbd.CH--C.sub.n H.sub.2n+1 where p is equal to 0 or 1 and n is an integer from 1 to 17, and the acids (X=OH) are prepared by hydrolysis of the amides thus obtained.
The acids and their salts may be employed as surface-active agents or, as also the amides, as intermediates for the synthesis of such agents.
