Application

4,4′-Oxydianiline can be used as a reactant to synthesize:
  • Aromatic polyamides by polycondensation with aromatic dicarboxylic acids.
  • Azomethine bisphenols by reacting with aromatic aldehydes, which can be used to synthesize polyazomethines by the oxidative polycondensation in the presence of NaOCl as an oxidant.
  • Polyguanamines by the chemoselective polycondensation with 2-amino-4,6-dichloro-1,3,5-triazine in the presence of potassium carbonate as a base.
It can also be used for the functionalization of carbon nanotubes, which can react with terminal dianhydrides to synthesize polyimide aerogels.
