This work describes the effect of the spherulitic growth of lamellar crystals on the morphology of a diblock copolymer rich in crystallinecomponent. For this study, solvent cast (PB)0.2(PCL)0.8 diblock copolymer films (510 micron) were annealed at below the orderdisorder transition temperature (ODT) and crystallized at below the melting temperature (Tm) of PCL. The microphaseseparated morphology was still intact after the formation of spherulites at below the Tm of PCL. The formation of supermolecular spherulites was investigated by polarized light microscopy (PLM) and the microstructure was studied using transmission electron microscopy (TEM).
