摘要：

Di- and tetra-amides have been synthesized from the esters of perfluoropolyetheric mono- and di-carboxylic acids and ethylenediamine, hexamethylenediamine and piperazine, and characterized by viscosimetric and osmometric determinations, FT-IR, H-1 NMR and F-19 NMR spectra. They were also submitted to stability tests in acidic and basic media, by UV irradiation and heating. The properties shown by the amides make them eligible as protective materials for stone exposed to atmospheric agents. Preliminary tests on the efficacy of these products on a bioclastic limestone (Pietra di Lecce) have provided very promising results.
