摘　　要：本研究首先通过原子转移自由基聚合(ATRP)方法制备了二嵌段共聚物,聚乙二醇-b-聚(甲基丙烯-2-甲氨基乙酯)(PEG-b-PDMAEMA),再通过对PEG-b-PDMAEMA的季胺化,制备了苯硼酸化的聚乙二醇-b-聚(甲基丙烯-2-甲氨基乙酯)(PEG-b-PBDMAEMA)。通过~1H-NMR谱图和GPC对PEG-b-PBDMAEMA进行结构表征,并利用DLS研究PEG-b-PBDMAEMA的水溶性。结果表明以季胺化为后改性手段,成功制备出水溶性良好的含苯硼酸二嵌段共聚物。In this paper,we prepared a diblock copolymer poly(ethylene glycol)-b-poly(2-(dimethyl amino)-ethanomethacrylate)(PEG-b-PDMAEMA)via atom transfer radical polymerization(ATRP),which was then quaternized to prepare phenylboronic acid-containing diblock copolymer PEG-b-PBDMAEMA.The structure was characterized via 1 H-NMR spectra and GPC.DLS was used to investigate the water-solubility of PEG-b-PBDMAEMA.The results showed that water-soluble diblock copolymer containing phenylboronic acid can be obtained through post-polymerization modification using quaternary reaction.
