  • Description: <jats:title>Abstract</jats:title><jats:p>Preliminary results regarding the physical behaviour of a stereoblock‐isotactic polypropylene are reported. The polymer was obtained using a soluble Ziegler‐Natta catalyst and films were prepared by pressure molding. The particular steric configuration is responsible of low crystallinity and small crystal size; the bulk structure can be represented by a fringed micellar model in which small crystallites act as physical crosslinks. The observed behaviour being typical of a thermoplastic elastomer well agrees with the suggested model.</jats:p>
