Under special crystallization conditions from the melt, both ␣and -forms of isotactic polypropylene were produced simultaneously. The ␣and -spherulites of polypropylene were differentiated under optical microscope, allowing the nanoindentation of individual spherulites of each crystallographic for
## Abstract Isotactic polypropylene (iPP) shows both double melting peaks and single melting peak depending on cooling rates and crystallization temperatures. This manuscript reviews the related studies. These melting behaviors can be explained based on two types of spherulite structures. Type I Sp
