摘　　要：在总结近年来国内外有关磁性高分子微球研究成果的基础上,对磁性高分子微球的四种制备方法,即共混包埋法、界面沉积法、活化溶胀法和单体聚合法的工艺过程及优缺点进行了概述。对磁性高分子微球的各项特征(如平均粒径、粒径分布、磁含量、磁响应性及耐酸碱性等)的表征方法进行了介绍。On the basis of summarizing the research efforts of magnetic polymer microsphere worldwide in recent years, the preparation of magnetic polymer microshpheres, including crossblend and embedment, interface aggradation , activation swelling and monomer polymerization, as well as relative merits of these processes, are reviewed. The characterization methods of magnetic polymer microsphere for some properties, such as average size, size distribution, magnetic particles content, magnetic response, acid-resistant and alkali proof ability, are introduced.
