| 摘 要： | 以２－溴异丁酸季戊四醇四酯为引发剂在ＣｕＢｒ／ｂｐｙ催化下实施苯乙烯和丙烯酸β－羟丙酯原子转移自由基共聚合，结果表明聚合物的分子量与理论分子量接近，聚合反应具有活性聚合的特征。进一步对聚合产物进行ＧＰＣ，Ｈ－ＮＭＲ，ＩＲ和羟值滴定分析，表明合成的星状共聚合物中同时具有苯乙烯和丙烯酸β－羟丙酯结构单元，而且羟基在聚合物中近似均匀分布。

| Abstract: | Catalyzed by CuBr/bpy, atom transfer radical copolymerization of styrene and 2-hydroxypropyl acrylate was carried out by using pentaerythritol tetra(2-bromoisobutyrate) (PT-Br) as an initiator. The results showed that the number average molecular weight is close to the theoretical value, which is characteristic of living polymerization. GPC curve, H-NMR spectrum,IR spectrum and hydroxyl number of the synthesized star copolymer reveal that the star copolymer molecule consists of styrene and 2-hydroxypropyl acrylate units and the hydroxyl groups approximate to distribute evenly in the star macromolecule. |
