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。Abstract: 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
