Abstract
Aromatic hydrogenated polymers comprising perfluoropolyether (PFPE) chains bonded to the aromatic rings to form sequences randomly distributed in the polymer structure, having the formula (I): (T-CFO—Rf—CF)-Tin which: n is an integer from 1 to 10; Tis an aromatic group of the backbone of the hydrogenated polymer, or alternatively condensed aromatic groups; Tmay be equal to T, or alternatively a functional group —COOH or —COF; Rf is a (per)fluoropolyoxyalkylene chain, in which the starting hydrogenated aromatic polymers are obtained by polycondensation, stepwise polyaddition or polyaddition of cyclic monomers in which the ring is formed by at least 3 atoms.
