Despite this approach can diminish the influence of interference from the substrate, the petroleum-based plastic products in the fire scene could produce a great deal of flammability gas and other products, which may cause interference with evidences of the fire debris. In this study , the degradation behaviors of PBT ans PA6 were investigated to understand the behavior of the combustion and pyrolysis of the two materials .The experimental results show that not only the PBT and PA6 but also the products made from PBT and PA6 produce aromatic compounds .Those aromatic compounpd may affect the judgment of the accelerants in the fire debris. On the often hand , FT-IR is used to elucidate the combustion behavior of the polymer.
