摘要:
通过原子转移自由基聚合(ATRP)与原子转移自由基偶合(ATRC)技术相结合,制备出了高分子质量多环拓扑结构聚合物。首先用甲基丙烯酸(α-溴异丁酰氧基乙基)酯(BiBEM),引发苯乙烯进行自由基聚合,制备出含溴末端的支化聚苯乙烯,并通过沉降分级得到高分子质量、低分散性聚合物。最终,以支化聚合物为前驱体,在极稀浓度条件下,通过ATRC反应,使其支链末端偶合成环,制备出高分子质量多环状支化聚合物。用核磁(1H NMR)、三检测体积排阻色谱仪(TD-SEC)、动静态光散射(DLS)对聚合物结构进行表征。结果表明,成功合成了结构明确、纯度较高的环状支化聚合物(c-BPS),聚合物表现出了高分子质量、低分散性的特性。
Abstract:
A facile and efficient method to construct a multicyclic branched polymer through combining atom transfer radical polymerization(ATRP)and atom transfer radical coupling(ATRC)technologies is introduced. Firstly, the branched polystyrene was prepared by ATRP using 2-(2-bromoisobutyryloxy)ethyl methacrylate(BiBEM)as the branching agent. And then Br terminal-Br terminal radical coupling of BPS was conducted through ATRC under a high dilute solution. The obtained multicyclic polymers(c-BPS)exhibit a rare characteristic of narrow dispersity and endless structure. The structure and property of the resulted polymers have been characterized by triple detection size exclusion chromatography(TD-SEC), nuclear magnetic resonance spectroscopy(1H NMR)and dynamic light scattering(DLS). The results show that the well-defined and high purity multicyclic branched polystyrene(c-BPS)have been synthesized successfully.
