Description
Summary:Within the framework of a project for the better understanding of the behaviour of polyethylene under specific operating conditions, the temperature influence on a polyethylene base resin was studied. A differential scanning calorimetry analysis has shown the effect of annealing on morphological changes. The first was noticed at 318 K while a sharp transition to an amorphous material was observed at around 373 K followed by Fourier transform infrared spectroscopy analysis of the double peak (730-720 cm exp -1 ), characteristic of crystalline and amorphous states. These observations are used to support the interpretation of conductivity measurements.
