What is Préparation de Polyesteramides Alternés about?
## Abstract The polycondensation of hydroxyamido acids of general formula HO‐R~1~‐CO‐NH‐R~2~‐COOH provides alternating polyesteramides only when R~1~ and R~2~ are alkyl groups. These aliphatic alternating polyesteramides, according to their structural high regularity, possess a more important content of interchain hydrogen bonds than the random copolymers. The higher melting point of the random copolymers is attributed to the heterogeneity of amide group partition in the chain. The existence of a benzyl group in the structure of the hydroxyamido acids reduces the polycondensation ability and the molecular weights of the products are low. These aromatic monomers are thermally degraded, __p__‐toluic acid evolving; ester and amide functions stoechiometric ratio is not maintained, but infrared and differential thermal analysis show that these aromatic polyestermides keep a reasonable structural regularity.
