摘要： 本文用扭辫分析(TBA)和红外光谱研究了双[4-(4-乙炔基苯氧基)苯基]砜(简称四苯醚砜双炔)及其聚合物的动态力学行为.TBA热谱的结果可以明显地表征四苯醚砜双炔的熔融及其低温区和高温区的化学反应特征,以及其聚合物的玻璃化转变和分解反应等物理-化学转变行为.实验表明四苯醚砜双炔聚合物的玻璃化温度Tg极大地取决于聚合条件.

Abstract: The polymerization processes of bis[4-(4-ethynylphenoxy)phenyl] sulfone and its polymer's dynamic mechanical properties were investigated by torsional braid ana-lysis(TBA) and infrared spectroscopy. Results showed that the multiple transitions including the melting, low-and high-temperature reaction of oligomer, glass transition and decomposition reaction of its polymer could be characterized in the TBAspectra. The glass transition temperatures of its polymers depend upon the conditions of polymerization.
