以Fe3 O4为核 ,采用分散聚合法 ,合成了粒径为 0 .5~ 2 .0 μm、单分散性好、磁含量可达 10 %的PSt、P(St/MAA)磁性高分子微球。讨论了温度、引发剂、分散介质、稳定剂等因素对反应结果的影响。对所得磁性微球的外观形态、磁响应性进行了表征。
P (St / MAA) magnetic polymer microspheres with a particle size of 0.5 ~ 2.0 μm and good monodispersity and magnetic content of up to 10% were synthesized by dispersion polymerization using Fe3 O4 as nucleus. . The effects of temperature, initiator, dispersion medium and stabilizer on the reaction results were discussed. The appearance and magnetic response of the obtained magnetic microspheres were characterized.
