摘要:
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: ##STR1## with D=O, S, or NH and where R* is the parent body of the dicarboxylic acid and the groups R.sup.1 through R.sup.4 are H, F, CH.sub.3, or CF.sub.3 (with a maximum of two CH.sub.3 or CF.sub.3 groups).
