聚芳醚砜热化学行为及表征

Study on the thermochemical behavior of polyether sulphone

用低温绝热量热、DTA、TG等方法测量了PES的热化学行为,得到了基聚醚砜(PES)低温下的Cp T曲线、玻璃化温度(tg)、熔融温度(tm)及热分解温度(td),从而为PES这种高分子材料的加工、改性及应用提供了热化学方面的基础数据.

*' The CpT relationship, temperature of glassing Tg, temperature of melt Tm, and temperature of thermal decomposition Td of polyether sulphone (PES) are obtained by lowtemperature adiabalic cacorimeter (LAC), thermogravimetry (TG), derivative thermogravimetry (DTG), differentiate thermal analysis (DTA), and useful data are provided for the processing, modification and application of PES.
