  Poly(THF‐b‐ECH‐b‐MMA) and poly(THF‐b‐ECH‐b‐S) block copolymers were synthesized by bulk polymerization of methyl methacrylate (MMA) and styrene (S) with poly(THF‐b‐ECH) initiators. The quantum chemical calculations for the block copolymers, the initiating systems of the cationic polymerization of THF and ECH were achieved using HYPERCHEM 7.5 program. The optimized geometries of the polymers were investigated with the

  开发了一种有效且新颖的单锅法，该方法可通过自由基捕获工艺（通过bis原位热分解）将原子转移自由基聚合（ATRP）引发剂固定在完全热解的碳硬球（CHS）的表面上。（溴甲基苯甲酰基）过氧化物。CHS在固定引发剂之前不需要任何其他准备处理。苯乙烯和甲基丙烯酸甲酯通过表面引发的原子转移自由基聚合（SI-ATRP）聚合到引发剂固定的CHS上。使用傅立叶变换红外，热重分析，扫描电子显微镜和透射电子显微镜对样品进行表征。这些表征方法证实，所有CHS均覆盖有均匀的接枝聚合物层。这种有效的一锅式ATRP引发剂固定化方法是使用SI-ATRP快速制备各种聚合物涂覆的碳基纳米材料的极其简单的途径。©2013 Wiley Periodicals，Inc.
