中文摘要：
采用无毒高活性的氯甲基辛基醚（CMOE）作为氯甲基化试剂,对聚醚酰亚胺（PEI）进行氯甲基化。考察了各种因素对氯甲基化反应的影响规律,优化了反应条件。溶剂用量、催化剂用量、反应温度等因素对反应有显著影响,最佳反应条件为：PEI∶CMOE∶C2H4Cl2∶ZnCl2=2.0 g∶4 mL∶50 mL∶1.0 g,反应温度60℃。在该条件下控制反应时间,成功合成了一系列不同取代度的氯甲基化PEI,取代度为21%~110%。
英文摘要：
The chloromethylation of poly（ether-imide）（PEI） was carried out by using non-toxic and high-efficient chloromethyl octyl ether（CMOE） as chloromethylation reagent.The effects of various factors on the chloromethylation reaction were studied,and the reaction conditions were optimized.The amount of solvent and catalyst,and the reaction temperature affected the chloromethylation of PEI significantly.The optimized condition is： PEI∶CMOE∶C2H4Cl2∶ZnCl2=2.0 g∶4 mL∶50 mL∶1.0 g at 60 ℃.Under optimum condition,a series of chloromethylated PEI with different substitution degrees ranging from 21% to 110% were prepared successfully by controlling the reaction time.
