This invention relates to compounds which simultaneously contain a perfluorinated chain and a hydrogenated chain and which correspond to the general formula: <IMAGE> in which RF is a perfluoroalkyl radical, m an integer from 0 to 2, RH an alkyl radical, X an OH or NR1R2 group, and R1 and R2 are hydrogen atoms or methyl radicals. The amides (X=NR1R2) are prepared by photoamidation of the polyfluoroolefins RF-(CH2)p-CH=CH-CnH2n+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. |
