Abstract
It was proposed earlier that the additional exothermic peak observed a t 350-degrees-C in differential scanning calorimetry of PAN fibre is a ssociated with certain intermolecular cross linking, as well as to the aromatization of structure, which results in a better stabilized stru cture. It has been further confirmed in the present study through infr ared spectroscopy that these reactions take place in the fibre and occ ur only in the presence of oxygen.
