摘要
以聚乙二醇单甲醚和丙烯腈为原料,在水相中合成了一端为羧基的聚乙二醇单甲醚,其结构经1H NMR和IR确证。讨论了反应时间、反应温度、溶剂和惰性气氛对反应的影响。
Carboxyl-monomethoxypoly( ethylene glycol)(CmPEG) was prepared from mPEG and ac-rylonitrile in water and the structure was characterized by 1^H NMR and IR. The influences of reaction conditions such as reaction time, temperature, solvent and inert atmosphere to the reaction result werediscussed.
