AbstractThe thermal decomposition behaviors of four chemically modified polyethylene were investigated by high resolution pyrolysis gas chromatography-mass spectrometry (HR PyGC-MS). The results revealed that substituents attached to maleated polyethylene as amides formed from secondary amines are significantly less stable than imides formed from primary amines. N-methylaniline amide-derivatives of maleated polyethylene undergo significant decomposition at 160 degrees C and substantial decomposition at 200 degrees C. In contrast,the imides (except aniline imide) derivatives of maleated polyethylene are stable for long periods of time at 160 degrees C,and the decomposition of phenethylamine imide-, 9-aminomethylphenanthrene imidederivatives is initiated slowly at 255 degrees C and 280 degrees C,respectively. The effect of different modified groups on thermal stability of the polymers was discussed based on the qualitative and quantitative determination of the products. The thermal degradation pathways for the above chemically modified polyethylene were suggested.
