采用Ｗｉｌｌｉａｍｓｏｎ反应合成了支化聚氧化乙烯，并在采用ＩＲ、１３ＣＮＭＲ、ＤＳＣ方法进行表征的基础上，采用静态先散射（ＳｔａｔｉｃＬｉｇｈｔＳｃａｔｔｅｒｉｎｇ，简称ＳＬＳ）、熔流指数（ＭｅｌｔＦｌｏｗＩｎｄｅｘ，简称ＭＦＩ）、动态热机械性能分析（ＤｙｎａｍｉｃＭｅｃｈａｎｉｃａｌＴｈｅｒｍａｌＡｎａｌｙｓｉｓ，简称ＤＭＴＡ）、导电性等方法，对掺盐以后聚合物的性质进行了表征及研究．ＳＬＳ和ＭＦＩ两实验表明样品中存在着接枝现象，由ＭＦＩ的测定表明了粘度的增加，聚合物与ＬｉＣｌＯ４混合物的Ｔｇ和Ｔｍ由ＤＭＴＡ测定．另外还对聚合物—盐混合物的导电性进行了测定．结果表明，支化和线型聚合物除在熔流指数上有所减少之外，在包括导电性能等方面并没有明显的差别．
The branched polyethylene oxide was synthesized by Williamson reaction. Based on the characterization by IR, 13CNMR and DSC methods, StaticLightScattering (SLS), MeltFlowIndex (MFI), dynamic thermo-mechanical Performance analysis (DynamicMechanicalThermalAnalysis, referred to as DMTA), conductivity and other methods, the nature of the polymer after salt doping characterization and research. Both SLS and MFI experiments showed that there was grafting in the sample. The increase in viscosity was confirmed by the MFI measurement. The Tg and Tm of the polymer and LiClO4 mixture were determined by DMTA. The conductivity of the polymer-salt mixture was also measured. The results show that branched and linear polymers have no significant differences in terms of conductivity, except for a decrease in melt flow index.
