“…The glass temperature characterizes the amorphous fraction as much as density and orientation or stretched position, as well as the related chain refolding and concentration of the amorphous molecules. The colloidal structure, which is created by the spatial arrangement of crystalline and amorphous section, is characterized by fibrils or paracrystalline layer lattices, the interphases between amorphous and crystalline areas, and by the creation of microvacuoles and cavities [1,6].…”
