温度对巯基封端液态聚硫橡胶结构的影响

Effect of temperature on chain exchange reaction of thiol-terminated liquid polysulfide

利用凝胶渗透色谱和核磁共振波谱分析,通过研究聚硫橡胶在温度变化时分子结构发生的变化,推断出温度变化时聚硫橡胶链交换反应模式。

The molecular structure change of polysulfide resulted from temperature change was studied by means of gel permeation chromatography and nuclear magnetic resonance. The model of chain exchange reaction with temperature change was concluded.
