Preparation of poly-o-hydroxyamides and poly o-mercaptoamides

In a process for the preparation of poly-o-hydroxyamides and poly-o-mercaptoamides, a bis-o-aminophenol or a bis-o-aminothiophenol is reacted with a dicarboxylic acid derivative of the following structure: with D=O, S, or NH and where R* is the parent body of the dicarboxylic acid and the groups R1...
