Morphological Implications of the Interphase; Linking Crystalline and Amorphous Regions in Semi-Crystalline Polymers

摘要

In semi-crystalline polymers, a range of morphologies can be obtained in which a chain may traverse the amorphous region between the crystals or fold back into the crystals leading to adjacent or non-adjacent reentry, depending on the molecular architecture and crystallization conditions. This causes topological variations on the crystal surface, thus affecting the mechanical properties. In this communication, we will address how the morphology on the crystal surface plays a prominent role in drawability. Materials chosen are branched polymers.
