Description
Summary:The thermal decomposition behavior of poly ( ethylene terephthalate) (PET) fabrics containing meso-1,2,3,4-tetrabromobutane (TBB) is investigated using thermogra vimetry (TG), differential thermal analysis (DTA), and pyrolysis gas chromatography- mass spectrometry (Py-GC-MS). Isothermal TG analysis proves that the presence of TBB has little effect on the thermal decomposition of PET. However, isothermal DTA data reveal that the absorbed TBB participates in some reactions in the condensed phase of PET. On the other hand, Py-GC-MS analysis reveals that bromine atoms exist in the thermal decomposition products of PET. Thus, vinyl groups are generated from PET by β-CH hydrogen transfer, and they then react with hydrogen bromide, which is produced by TBB, to form bromine-containing thermal decomposition products. These facts show why TBB molecules, which have strong affinities for PET segments, are effective for Hame retardation.
