| Abstract: | 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. |
