Abstract
Summary: Poly(arylene ether amine)s were synthesized by a nucleophilic aromatic substitution polycondensation of bis[4‐fluoro‐3‐(trifluoromethyl)phenyl]amine with several bisphenols. Even though the monomer has an electron‐donating diphenylamine moiety, which normally deactivates a nucleophilic aromatic substitution (S~N~Ar) reaction, the polymerization proceeded by a S~N~Ar reaction to give high‐molecular‐weight polymers. The polymers show good solubility in common organic solvents and have __T~g~__s in the range of 123 °C to 177 °C.
High‐molecular‐weight poly(arylene ether amine)s synthesized by a S~N~Ar reaction with the monomer containing an electron‐donating diphenylamine moiety.
