Synthesis of poly(arylene ether amine)s from a monomer containing an electron-donating amine group in a nucleophilic aromatic substitution reaction
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 (SNAr) reaction, the polymerization proceeded by a SNAr reaction to give high-molecular-weight polymers. The polymers. The polymers show good solubility in common organic solvents and have T(g)s in the range of 123degreesC to 177degreesC.
