摘要
通过对聚合物的GPC谱图分析及紫外光谱测试,证明了二苯胺(DPA)在CumCl/TICl_4和DiCumCl/TICl_4体系中,既能捕获质子,又能稳定活性中心。提出了DPA在异丁烯阳离子聚合反应中的作用机理。
Summarizing and comparing the results of GPC traces and UV spectroscopy. We have demonstrated that added electron donor DPA in the CumCl/TiCL4 and DiCumCl/TiCL, system can not only trap H+ proton but also stabilize the living center in polymerization system , and showed the effecting mechanism of DPA in isobuthylene cationic polymerization.
