摘要: 通过模型化合物ArOArCOArArCOArOAr(Ar为苯基或1,4-亚苯基)的全优化结构,得到芳环之间的平均二面角为37.5°,由其结构参数建立了刚性链聚物分子结构与其熔点及玻璃化温度的关系式。据此较好地预测了新品种均聚物的热性能。

关键词: 刚性链分子结构, 二面角, 熔点, 玻璃化温度

Abstract: The full optimization structure of model compound ArOArCOArArCOArOAr is presented with average dihedral angle of 37.5°,Based on this ,the molecular structure is related to the melting point and glass transition for poly (aryl ether ketone) s and poly(arylether sulphone) s family with rigid molecular chain, The obtained relationship between them is well extended to predict the heat properties of the new family of aromatic homopolymers.

Key words: Molecular structure of rigid chain, Dihedral angle, Melting point, Glass transition temperature
