【摘要】 使用差示扫描量热(DSC)仪和差热-热重联用(TG-DTA)仪,利用氧化降解反应等温动力学法并结合起始氧化温度和氧化诱导期测定等实验方法,综合考察了聚醚用10种抗氧剂的抗氧化性能。结果表明,这10种抗氧剂对聚醚氧化降解反应的影响可分为3种类型。提出了评价每种类型抗氧剂的方法。更多还原

【Abstract】 The antioxidation ability of 10 kinds of antioxidants to polyether was studied with differential scaning calorimeter (DSC) and simutaneous thermogravimetric analyzer-differential thermal analyzer(TG-DTA) using oxidation reaction isothermal kinetics method combination with other experimental methods such as oxidation temperture(OT) and oxidation inductive time (OIT) measurement etc. It was discovered that the influence of 10 kinds of antioxidant on the ox-idative degradation reaction of polyether can be classified into 3 types. The methods to evaluate the antioxidation ability of each type of antioxidants have been pointed out.更多还原
