The main laws governing the thermal transformations in vacuum of phenylquinoxalines, which are compounds which simulate the elementary units of polyphenylquinoxalines are studied. These reactions involve a radical-chain mechanism. The initiation stag

The main patterns of the thermal degradation of polyphenylquinoxalinesin vacuo have been studied. It is shown that the thermal conversions of these substances follow the radical chain mechanism in two stages. First is crosslinking of the macromolecul
