A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

合成了带含环氧基侧链和十八烷基侧链的聚(马来酸二缩水甘油酯-co-甲基丙烯酸十八酯)，用~1H NMR对所得的共聚物进行了表征；研究了其在选择性溶剂中的自组装行为，发现P(DGMA-co-SMA)／THF／EtOH体系可以通过自组装形成囊泡形自组装体和支化的管状自组装体，P(DGMA-co-SMA)／THF／H_2O体系最初自组装形成球形自组装体，随着陈化时间的延长，球形自组装体逐渐融合成长条形自组装体和线形自组装体；探讨了自组装过程的机理，建立了可能的自组装过程模型。

The two acids were copolymerized with potassium persulfate as the initiator.
