| Abstract: | he pyrolysis of various polyphenyl-as-triazines (As-PPT) has been investigated by high resolution pyrolysis gas chromatography-mass spectrometer (HR PyGC-MS) and thermogravimetry (TG) in order to gain some insight into their degradation mechanism.The high resolution pyrograms of PPTs were obtained at the pyrolysis temperature of 650-950℃ with good reproducibility. More than 12 of the pyrolysates of AsPPTs were identified by MS. Combining with the TG data, the thermal degradation fmechanism was suggested in this paper. |
