Synthesis of Poly(arylene ether amine)s from a Monomer Containing an Electron‐Donating Amine Group in a Nucleophilic Aromatic Substitution Reaction

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. image High‐molecular‐weight poly(arylene ether amine)s synthesized by a S N Ar reaction with the monomer containing an electron‐donating diphenylamine moiety.
