聚芳醚腈砜的结构与热性能的研究

Study on the Structure and Thermal Properties of Poly (arylene ether nitrile sulfones)

本文采用红外光谱方法对聚芳醚腈砜的结构进行了分析，并与间苯型聚芳醚砜的结构作了对比，利用ＴＧＡ、ＤＴＡ等热分析测试，对不同分子量聚芳醚腈砜的热氧稳定性、玻璃化转变温度等热性能进行了研究。

お? The structure of poly (arylene ether nitrile sulfones) was examined through the infrared absorption spectra method in this paper and compared with the structure of resorcinol poly (arylene ether sulfones).The thermalgravimetric analysis (TGA) and differential thermal analysis (DTA) were used to investigate the thermaloxidative stability and the glass transition temperature of poly (arylene ether nitrile sulfones) samples with different average molecular weight.
