摘要
Thermal stability and degradation mechanism of acryIonitrile-2- hydroxyethyl methacrylate copolymer were investigated by pyrolysis gas chromatography/mass spectrometry (PyGC/MS). The study showed that the thermal stability of copolymer decreases with the increase in the starting acrylonitrile/( 2-hydroxyethyl methacrylate) molar ratio yield at 400'C. Its maximum decomposition temperature ranges from 400 'C to 500 'C and is not associated with its constituent components. The pyrolytic decomposition embodies the addition of the two monomer's pyrolysis products. The result has certain guiding significance to the application of the copolymer.
