摘要
从分子设计出发，合成了一种用于制备镶嵌荷电膜的新材料：聚（４－甲基苯乙烯－异戊二烯－苯乙烯－异戊二烯－４－甲基苯乙烯）三元五嵌段共聚物（ＭｓＩＳＩＭｓ），并用ＦＴＩＲ，１Ｈ－ＮＭＲ，ＧＰＣ，ＤＳＣ，ＴＥＭ等对共聚产物进行了表征。
A new polymer,poly (4-methylstyrene-isoprene-styrene-isoprene-4-methylstyrene) pentablock copolymer, was prepared by sequential anionic polymerization based on the molecular design. The structure of the pentablock copolymer was characterized by FTIR, 1 H-NMR, GPC, DSC, TEM, etc. The results show that the pentablock copolymer has a narrow molecular weight distribution and fine lamellar microstructure, and can be used as an ideal membrane material for the preparation of charge-mosaic membrane.
