Synthesis and phase behaviour of aromatic poly (esteramide)s

The synthesis of a series of aromatic poly(esteramide)s and the initial characterisation of these materials is reported in this paper. The polymers were prepared by transesterification polycondensation of various bis(p‐alkyl benzoate) aliphatic diamides with diols of differing lengths. Most of the polymers gave multiple endothermic peaks during heating in the DSC, and polarising optical microscopy revealed a number of different types of spherulites. X‐ray diffraction and infrared spectroscopy were used to probe the molecular correlations in the various crystalline phases. No evidence was found for liquid crystallisation.
