Novel melt‐processable molecular composites were obtained from isotactic polypropylene (iPP) and liquid‐crystalline oligoester (LCO). The nanostructure and thermal behaviour of molecular composites were examined by real‐time synchrotron small‐angle X‐ray scattering and wide‐angle X‐ray diffraction methods, and differential scanning calorimetry. The synthesized oligoester, with low melting temperature (391 K), exhibits the ability to form a thermotropic mesophase. It was shown that strong rigid rod‐like macromolecules of LCO are dispersed at the molecular scale in iPP matrix and act as reinforcing fibres.
