【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、13CNMR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。更多还原

【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 （）¹³C 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_<sub>PMMA=0.31) were discussed with the help of SEM and AFM.更多还原
