The theromo‐oxidative decomposition, flash ignition and burning of high‐impact polystyrene containing the flame‐retardant system decabromodiphenyl oxide + antimony trioxide was investigated using the Setchkin apparatus combined with mass spectrometry. The time dependences of the release rate of the main products into the gas phase during decomposition and burning showed that the flame‐retardants markedly influence these processes. It was found that the retardants used exhibit an acceleration of the polymer degradation and that the efficiency of inhibition in the gas phase depends on the atomic ratio antimony: bromine.
