ABSTRACT OF THE DISCLOSURE Compounds suitable as lubricants, having general formula: I) RO-(C3F6O)m-(CFXO)n-CFX-L or II) R"CFXO-(C3F6)x (CFXO)y-(C2F40)z-CFX-L, where R = -CF3, -C2F5, -C3F7, X = F, -CF3, R" = F, -CF3, -C2F5, m = an integer from 3 to 100, n = a finite integer, or = zero, wherefore m + n ranges from 3 to 100, provided that, if n is finite, n/m ranges from 5 to 20 and R is preferably = CF3, if n = zero, R is preferably -C2F5 or -C3F7, x = a finite integer, or - zero, y,z = finite integers, such that x+y+z ranges from 5 to 200, while Image ranges from 5 to 0.5 provided that when x = zero, z/y ranges from 1 to 0.5 and y + z ranges from 5 to 200 n while X is preferably F, and R" = L, L = group Y-Z, where Y = -CH2O-, -CH2-OCH2, -CF2, -CF2O , Z = a non- aromatic, non-fluorinated organic radical free from activated hydrogen atoms, containing two or more heteroatoms, which are electron doublet donors, or an aromatic radical, either or not containing heteroatoms, capable of giving rise to coordinative bonds or to charge-transfer bonds, thus causing various kinds of adsorption phenomena on metallic, polymeric or ceramic surfaces.
