A sulfur-bearing substituent, 2-thiazolidinethione, poly (organophosphazene) with side groups of this substituent and its metal polymer complex with cobalt (II) were synthesized and characterized. The structures of these compounds were investigated by means of IR, UV, DTA, EA and 1H NMR. The relationship between the structure and properties of poly (organophosphazene) was discussed. The results show that the poly (organophosphazene) with 2-thiazolidinethione has better thermal stability than the ligand investigated by TGA. Furthermore, the metal polymer complex showed an electroactivity due to the Co2+/Co3+ redox process confirmed by CV.

In this paper, polyorganophosphazene with electroactive property was synthesized by introducing pendant aniline dimer groups. Its structure was characterized by IR and 1H NMR spectrometry. Moreover, its electroactive property and thermal stability were investigated by means of cyclic voltammetry and thermal gravity analysis, respectively. As shown from these results, this polymer not only possesses better thermal stability but also still retains electroactivity.

The syntheses and spectroscopic properties of three difunctional photorefractivemodelmolecules ethyl [2-cyano-3-(9-ethylcarbazol-3-yl)] acrylate (ECEA), 2-(4-nitrophenyl)-3-(9-ethylcarbazol-3-yl)-acrylonitrile (N PEA) and 9-ethylcarbazol-3-azo-(4-nitrobenzene) (ECAN) are reported in th is paper. The results indicate that the spectroscopic properties are influenced by the structure of three molecules and these molecules belong to p-type sem iconductor.

采用传统的亲核取代反应的方法合成了一种新的含有咔唑侧基的有机磷腈高分子,并用红外、1H核磁、紫外、热失重、差热分析了其结构。它的玻璃化转变温度为91.6℃,大大低于聚乙烯咔唑(PVK)的玻璃化转变温度。

采用全自动扭辫仪和驻波管对PU/PMMA IPN体系的阻尼行为进行了研究。T BA结果表明,填料的最佳填加量为10%。吸音系数测试表明,常温时该种结构的IPN材料的吸音系数与频率近似成峰形,最大吸收在3000Hz左右。最好的吸音材料的吸音系数峰值为50%以上。
