THERMAL ANALYSIS OF A POLYPHENYL-as-TRIAZINE,
Abstract
A well-characterized poly(phenyl-as-triazine) was pyrolysed under dynamic and isothermal conditions in vacuum and in air. Simultaneous thermogravimetric, differential thermal and thermobarometric analysis of polymer films indicate a multistage thermal decomposition. An exothermic reaction between 305 and 465C was shown to involve the asymmetric triazine ring. This leads to the formation of a stable intermediate symmetrical triazine and nitrilic products, primarily benzonitrile. Based on the data, a degradation scheme initially involving the scission of the nitrogen-nitrogen bond in the asymmetric triazine ring was postulated. (Author)
