摘　　要：大粒径磁性高分子微球的制备邱广明邱广亮＊（内蒙古工业大学电力学院动力系呼和浩特）（内蒙古师范大学生物系呼和浩特０１００２２）关键词高分子磁性微球，苯乙烯，丙烯酸，共聚物，制备１９９６－１１－２５收稿，１９９７－０６－１１修回内蒙古自然科学基金资助项目...Copolymerization of styrene and acrylic acid in ethanolwater medium dispersed with magnetite particles of 30 nm diameter was carried out using potassium persulfate as initiator. The affinity among the magnetite particles, monomers and initiators was improved by coating the magnetite particles with polyethylene glycol. The effects of polyethylene glycol, dispersion medium, initiator and polymerization time on the formation of magnetic polymer microspheres have been investigated. Magnetic polymer microspheres of 30￣1000 μm diameter were prepared.
