ABSTRACT:
A method for producing poly-o-hydroxy amides by heating a dicarboxylic acid to a temperature .gtoreq.80.degree. C., together with a sulfonic acid chloride and a tertiary amine in a suitable solvent, to form a reaction mixture and reacting the mixture obtained with a bis-o-aminophenol solution at a temperature <80.degree. C.
