摘要
介绍了采用液相电导法测定氯化氢脱析速率,从而测试聚氯乙烯树脂稳定性的方法,该方法能提供PVC树脂脱HCl的诱导期、降解速率及降解全过程的信息,与刚果红和老化白度法相比,能确切地反映树脂的热稳定性。
The method of using liquid-phase determined hydrogen chloride desorption rate and the thermal stability of PVC resin was introduced. Induction period of PVC resin removing hydrochloric acid and the information of degradation rate were provided by PVC resin. The whole process of degradation was also provided. Comparing Congo red with aging whiteness method, the stability of PVC resin was showed exactly.
