Popis:	The mechanism of evaporation of Sb2O3 and the mechanism of formation and evaporation of antimony trihalides (SbX3) from Sb2O3 + halogen, which play important roles in the flame retardation of plastics, have been studied in the case of chlorine- and bromine-containing additives at different Sb/X mole ratios by means of complex thermal analysis, and massspectrometers. The temperatures of SbCl3 formation and its evaporation have been determined for PVC and Cerechlor 70 as chloride donors. The formation of SbBr3 could not be verified when Flammex (decabromodiphenyl ether) was used. A close correlation has been found between conventional and atomic absorption thermoanalytical curves recorded under identical experimental conditions. The atomic absorption detection of the thermally evolved products provides valuable information on flame retardation process.
