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乙烯基吡啶—异戊二烯—苯乙烯—异戊二烯—4乙烯基吡啶)(PISIP)五嵌段共聚物,并用IR、NMR、GPC、DSC等方法对共聚物结构进行了表征.
A new polymer, the poly(4 vinylpyridineisoprenestyreneisoprene4 vinylpyridine) pentablock copolymer, was prepared by sequential anionic polymerization based on the molecular design. The structure of the pentablock copolymer was characterized by FTIR, ’H NMR, GPC, DSC, 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.
