The morphology of β-modification of isotactic polypropylene (β-IPP) has been studied by polarizing microscope (PLM) and scanning electron microscope (SEM). Under PLM β-IPP appears as colored spherulites with twig-like structure. SEM photographs of β-IPP give petal-like and twist curve lamellar structure. A model for β-IPP spherulites growth has been advanced.
