超支化聚α-溴丙烯酸甲酯的合成及表征
Synthesis and characterization of hyperbranched poly(methylα-bromoacrylate)
【摘要】 用原子转移自由基聚合制备了超支化聚α-溴丙烯酸甲酯。用傅里叶变换红外光谱仪跟踪聚合过程并测出单体转化率,研究了聚合动力学,用三检测体积排除色谱、核磁共振和元素分析表征了聚合物的结构。
【Abstract】 Hyperbranched poly(methylα- bromoacrylate) was prepared by a one- pot atom transfer radical polymerization.The polymerization process was tracked by FTIR.The ratio of the area of C C to that of C O of the sample gave the conversion of the monomer.The structures of the hyperbranched polymers were confirmed by the tri- detector SEC,1H- NMR and element analysis.
