Pyrolysis-Gas Chromatography-Mass Spectrometry Analysis of Polyamid-6,T

Polyamid 6, T was conducted the pyrolysis under the temperature of 500 ℃. Twenty one kinds of the pyrolytical products of the polyamid 6,T were detected by pyrolysis gas chromatography mass spectrometry (Py GC/MS). The result showed that the pyrolytical products are mainly composed of benzonitrile, 1,4 benzenedicarbonitrile, N alkyl benzamide, N alkenyl benzamide, N alkyl 4 cyano benzamide and N alkenyl 4 cyano benzamide. The bond rupoure occured on the amido bond and the link between phenyl and amido. It provided a useful method for identifying polymer materials.
