Perfluoroalkylated monomers and polymers

Abstract

Abstract Trifluoromethyl‐, pentafluoroethyl‐ and other perfluoroalkylbenzenes ( 2a–d , 4 and 3 ) were prepared by the reaction of the corresponding aromatic halides with perfluorocarboxylic acids in the presence of copper(I) iodide. These products were modified by oxidation or (and) substitution reactions and subsequently polymerized to give perfluoroalkyl‐substituted polyamides, polyesters and poly(thio‐1,4‐phenylene)s showing good solubility.
