AbstraetmThe thermal degradation of polyacrylonitrile has been studied using the techniques of thermogravimetry, differential thermal analysis and thermal volatilization analysis. The influence of experimental conditions on the results is examined. The very sharp exothermic reaction below 300 ° is a
AbstractmThe thermal oxidation of polyacrylonitrile at temperatures between 200 ° and 375 ° has been studied. Samples produced by the heating of polyacrylonitrile fibre at various temperatures within this range, for periods of up to 5 hr, were analysed for carbon, hydrogen, nitrogen and oxygen. A co
Al~traet--The thermal behaviour of polyacrylonitrile studied by DTA and TG is shown to be greatly influenced by the presence of various types of additive. Pure PAN exhibits a very sharp exotherm at about 260 °, caused by the oligomerization of nitrile groups. This reaction can be initiated at much l
