Abstract: It was proposed earlier that the additional exothermic peak observed at 350°C in differential scanning calorimetry of PAN fibre is associated with certain intermolecular cross linking, as well as to the aromatization of structure, which results in a better stabilized structure. It has been further confirmed in the present study through infrared spectroscopy that these reactions take place in the fibre and occur only in the presence of oxygen.
