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

Comparison of the thermal behaviour of polyacrylonitrile with that of a-substituted polymers (polymethacrylonitrile, poly(a-phenyl acrylonitrile), poly(a-chloroacrylonitril¢) and poly(vinylidene cyanide)) shows that there is much less tendency for oligomerization of the nitrile groups in the substit

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

Acidic comonomers exert a strong initiating effect on the exothermic nitrile group oligomerization in polyacrylonitrile. In contrast to the sharp intense transitions for pure homopolymers, the exotherms for the copolymers are very broad with much reduced differential temperatures. This is explained
