摘要: 采用阴离子聚合技术合成了一系列苯乙烯-甲基丙烯酸甲酯的两嵌段共聚物(PS-b-PMMA).采用GPC、FTIR、NMR(1HNMR、13CNMR和固体NMR)和DMA等手段进行了表征.结果表明,所得产物为高分子量、窄分布、具有微相分离结构的两嵌段共聚物.

Abstract: Aseries of diblock copolymers of styrene and methyl methacrylate weresynthesized via sequential anionic polymerization.The products are diblock copolymers with highmolecular weight and narrow molecular weight distribution.The microphase-separatingstructure is proved by the information obtained from DMAand the solid state NMR.Themorphology structure is closely related to the ratio between XPMMAand XPS.

Key words: Block copolymer, Polystyrene, poly (methyl methacrylate), Anionic Polymerization morphology
