Synthesis of novel ordered poly(ester‐amide)s

摘要: Five different completely aromatic, ordered poly(ester-amide)s 6a — e were prepared from diphenols 5 and 4,4′-carbonyliminodibenzoyl dichloride (3). This bifunctional “amide-acid chloride” was synthesized in two steps by oxidation of 4,4′-dimethylbenzanilide (1) with permanganate under neutral conditions subsequent reaction thionyl chloride. The polymers obtained characterized IR spectroscopy viscosity measurements. Their physical properties like density, solubility, thermal behaviour also studied.
