| Abstract: | The structures of PET and PBT are so similar that it is difficult to identify them by Infrared spectroscopy.A pyrolysis gas chromatographic method with steer capillary column was established for identification of PET and PBT.The temperature of pyrolysis and the separation conditions were optimized.The method is simple,rapid and accurate. |
