The Microstructure of quenched and annealed iPP films was investigated by means of differential scanning calorimetry (DSC), density measurements, wide-angle X-ray diffraction (WAXD) and dynamic mechanical spectrometry (DMS). It was found that quenched iPP can be described as a biphasic material cons
The lattice parameters of a highly stereoregular metallocene polypropylene crystallized at 145ЊC were obtained after cooling and heating cycles in a temperature interval between 25ЊC and 165ЊC. The b dimension undergoes a large thermal expansion with temperature (0.6 A ˚) while the change of the a a
