With trimethyl,4-dodecylbenezyl ammonium chloride and 18-crown-6 as pase-transfer catalysts, the azidation of polyepichlorohydrin in poly and H2O were studied. The reaction discipline and mechanism were discussed. The results show that the system with trimethyl, 4-dodecylbenezyl ammonium chloride as phase transfer catalyst and PEG as medium is a safe and effective approach to glycidyl azide polymer preparation, and azidational ratio of PECH can reach 97% above within 15 h.

Saturated Ag/AgCl. Furthermore, in situ UV-Vis spectra showed that the electrocopolymerization between m-toluidine and p-phenylenediamine was performed. The p-phenylenediamine might react with m-toluidine to yield more active intermediates, which not only promote polymerization but also accelerate polymerization. In addition, through that p-phenylenediamine could be incorporated into copolymer to make the copolymer have a phenazine or phenazine like cyclic structure, which was proved by the FTIR of polymers.

在恒电位电解的条件下，相应的原位紫外-可见光谱和聚合物的傅立叶变换红外光谱表明间甲基苯胺和对苯二胺能发生电化学共聚反应，由于对苯二胺可能与间甲基苯胺形成了具有较强反应活性的中间体，使得对苯二胺的加入不但促进和加速了聚合反应，而且还结合进聚合物中形成了phenazine或类似于phenazine的环结构。
