Abstract	The gaseous species present above samples of polystyrene containing Sb[2]O[3] and selected chlorinated paraffins, tetrachlorobisphenol A and tetrabromobisphenol A were determined by atmospheric pressure chemical ionization mass spectrometry during exposure to radiant heat in the presence of air. SbOCl[3], SbCl[3](OH), SbCl[4], and SbCl[3](OH)[2] were found to be present in greater amounts than SbCl[3], the species normally identified with the fire retardant activity of Sb-halogen systems. Mass spectral analyses were performed on the vapour above SbCl[3] in air at atmospheric pressure and room temperature, to identify these species produced from the reaction between Sb[2]O[3] and the chlorine source.
