摘　　要：采用原子转移自由基聚合(ATRP)方法,制备聚苯乙烯(PS)接枝型引发剂,进而引发甲基丙烯酸丁酯(BMA)与丙烯酸镉(ACd)的共聚合,成功获得PS-g(BMA-co-ACd)接枝共聚物金属络合物。通过傅里叶变换红外吸收光谱、等离子体发射光谱、热重分析对共聚物的组成、结构和性能进行了分析。结果表明,聚合物金属络合物中镉含量测试值与理论值相近,其热稳定性随着镉金属含量的增加稍有降低;通过扫描电镜、透射电镜对聚合物金属络合物在水溶液中自组装形态进行分析,发现其在水溶液中自组装成球形结构的粒子,且稳定性较好;抑菌性测试表明其对大肠杆菌、枯草芽孢杆菌、金黄色葡萄球菌有较好的抑制作用。A polystyrene（ PS） graft initiator was prepared through atom transfer radical polymerization（ ATRP）. The initiator was used to trigger copolymerization of butyl methacrylate（ BMA） and acrylic acid cadmium（ ACd）. Finally,PS-g（ BMA-co-ACd） graft copolymer metal complex was obtained successfully. The composition,structure and property of the polymer were characterized by FT-IR,plasma emission spectroscopy,thermal gravimetric analysis（ TGA）,which is found that the content of cadmium in polymer metal complex is close to the theoretical value,and as the increasing content of ACd,the thermal stability of polymer metal complex slightly decreases. The self-assembly topography of this polymer metal complex in water via SEM and TEM analysis shows stable spherical structure. Biological tests indicate that against Escherichia coli,Bacillus subtilis,Staphylococcus aureus,materials have better antibacterial activity.
