摘要
用裂解色谱法对环化聚丁二烯进行了表征。分离鉴定了主要裂解产物,观察了裂解温度对主要产物组成的影响,并同线型的高顺式1,4-聚丁二烯的裂解行为作了对照,从分子链结构的角度,对主要裂解产物产率和热重曲线的变化以及裂解温度特性进行了相应的解释。
Thermal degradation of cyclized polybuladiene (CPBD) has been studied using pyrolysis gas chromatography. The main pyrolytic products were separated and identified. The influence of temperature on the yield of main products has been examined. The pyrolytic behavior of CPBD was compared with that of cis-1,4 polybutadiene and elucidated in terms of the structure of molecular chains.
