| 摘要 |
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): (T1-CF2O—Rf—CF2)n-T3 in which: n is an integer from 1 to 10; T1 is an aromatic group of the backbone of the hydrogenated polymer, or alternatively condensed aromatic groups; T3 may be equal to T1, 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. |
