Several aromatic polyamides were prepared from aromatic dicarboxylic acids with two diamines containing carbonyl and ether connecting groups between the aromatic rings; the phosphorylation route was used. The synthesis of these diamines involves a nucleophilic displacement reaction in dipolar aproti
