In this paper, a series of PEG macroinitiators were prepared by the reaction between monodisperse PEG and 2-bromoisobutyryl bromide, and the synthesis of the ABA-type amphiphilic triblock copolymers with the photo-sensitive property (PFM (1)C-b-PEG-b-PFM (1)C) via atom transfer radical polymerization with CuCl/N, N, N′, N″, N″-pentamethyldiethylenetriamine (PMDETA) complex as the cat.
以单分散的聚乙二醇和2 溴异丁酰溴为原料,通过酰溴化反应制备了一系列大分子引发剂,继而利用原子转移自由基聚合技术合成出了结构明确的ABA型光敏性双亲嵌段共聚物,并用红外光谱仪、紫外可见分光光度计、核磁共振仪和凝胶渗透色谱仪等对产品的结构进行了表征,由于能吸收紫外光的肉桂酰基在聚合后得以保留,该聚合物具有一定的光敏性。
