摘要
采用Ｗｉｌｌｉａｍｓｏｎ反应成功地合成了支化聚氧乙烯。并用ＩＲ、１３ＣＮＭＲ、ＤＳＣ对其进行了表征。结果表明，１３ＣＮＭＲ可半定量地表征支化度，链的支化可以降低玻璃化温度和结晶度。
branching poly oxyethylene (PEO) was synthesized by williamson reaction, and can be dissolved in some organic solvents such as methylene chloride. tetrahydrofuran and N, N-dimethyl acetylamide.The structure or branching PEO were been characterized by 13C NMR, IR, GPC and DSC. It indicates that the glass transition temperature and crystallinity of PEO was decreased due to the branching.
