Homopolymers and block copolymers of higher epoxides (butene oxide and hexene oxide) are synthesized using 1-alkanols and polyethylene glycol monomethyl ether (PEG-MME) 1100 as initiators by anionic ring opening polymerization in bulk. Most of the samples were synthesized with controlled microwave heating in sealed vessels. Tri- and tetrablock copolymers with different repeat units in the individual blocks are synthesized by living polymerization with addition of the next monomer after complete consumption of the previous one. The products thus obtained are characterized using size exclusion chromatography (SEC), liquid chromatography under critical conditions (LCCC) and liquid adsorption chromatography (LAC).
使用1-链烷醇和聚乙二醇单甲醚（PEG-MME）1100作为引发剂，通过本体阴离子开环聚合反应合成了高级环氧化物（氧化丁烯和氧化己烯）的均聚物和嵌段共聚物。大多数样品是在密封容器中通过控制微波加热合成的。通过在消耗完前一种单体后添加下一种单体进行活性聚合反应，合成了各个嵌段中具有不同重复单元的三嵌段和四嵌段共聚物。使用尺寸排阻色谱法（SEC）、临界条件下的液相色谱法（LCCC）和液相吸附色谱法（LAC）对由此获得的产物进行表征。
