摘　　要：研究了聚氯乙烯在有氧存在时 ,受热过程中的脱 HCl分解与氧化降解反应 ,利用 FT- IR- 1 0 DX红外光谱仪 ,在高温、高压下 ,用原位红外 ,跟踪扫描的技术 ,证实了棉酚衍生物 AG对软质聚氯乙烯的热氧稳定作用 ,对延长软质聚氯乙烯的氧化诱导期有较好的效果。The decomposition via hydride chlorine and the oxidation degradation of the PVC in the presence of oxygen have been investigated with in situ IR infrared technique under high temperature and high pressure.When the gossypol derivative AG was added to the soft poly(vinyl chloride),the heat stable and antioxygenation of it has been confirmed in our experiments. It has also been found that oxidation induction period of the soft poly(vinyl chloride) containing the gossypol derivative AG increases remarkably.
