    Synthesis of P(St-b-MMA) and Preparation of Nanoscopic Membranes

      摘要
    • 摘要: 采用阴离子聚合技术合成了苯乙烯(St)和甲基丙烯酸甲酯(MMA)的两嵌段共聚物P(St-b-MMA)，探讨了环己烷／四氢呋喃混合溶剂对聚合的影响，采用FTIR、^13C NMR等表征产物结构及成分，并以P(St-b-MMA)(聚甲基丙烯酸甲酯链段质量分数为0．31)制备了具有纳米孔洞的高分子薄膜。

       

      Abstract: A series of diblock copolymers of styrene and methyl methacrylate were synthesized via (sequential) anionic polymerization. The products are proved by FT-IR and ()~(13)C NMR. The influence of solvent has been investigated, showing that well-controlled anionic polymerization can be realized in the mixture solvent of hectane and THF. In addition, the preparation of polymer films with holes at the position of PMMA microphase (w__(PMMA)=0.31) were discussed with the help of SEM and AFM.
