Thermally decomposition products from virgin and flame retarded polyesters were investigated by using GC-MS method. Effects of flame retardation on polyester were found to appear at relatively lower temperature. Difference between retardants which contain phosphorus or bromine was shown clearly. Phosphorus-containing polyester emitted more amounts of carbon monoxide, carbon dioxide, and benzene than other polyesters. Bromine-containing polyester emitted less amounts of gaseous products than other polyesters.
