Synthesis of Poly(arylene ether amine)s through Nucleophilic Aromatic Substitution Reaction (SNAr) |
초록 |
Poly(arylene ether)s usually have been prepared via SNAr reaction of activated dihalo- or dinitro-substituted monomers and diols, because the oligomeric polymers are obtained with unactivated monomer systems even at high temperature and long reaction time. In this research, poly(arylene ether)s containing aromatic amine units were synthesized via nucleophilic aromatic substitution reaction of the novel monomer, bis(4-nitro-3-trifluoromethylphenyl)phenylamine and bis(4-fluoro-3-trifluoromethylphenyl)amine, with several bisphenols. Hyperbranched poly(arylene ether amine)s were also synthesized by one step polymerization of the novel monomer, 4-[bis(4-nitro-3-trifluoromethylphenyl)amino]phenol. Even though the monomer has diphenylamine or triphenylamine group which is a deactivating group for SNAr reaction, the polymerization proceeded successfully. It seems that the electron-withdrawing effect of trifluoromethyl group at the ortho position of the leaving groups is large enough to suppress the negative effect of the amine group. The detailed reaction behavior and properties of polymers will be discussed. |
