| 摘 要： | 详细地研究了乳化剂用量对种子乳液聚合反应的影响，并成功地制备出粒径约为３００的苯乙烯／丙烯酸共聚小球。另外，还报道使用化学共沉淀法使无机粒子与高分子球复合，制备出高分子球为核，无机粒子为壳层的磁性复合料子，使用ＸＲＤ、ＴＥＭ等手段对此复合料子进行了表征。同时，进一步研究了这种复合粒子悬浮液的悬浮性能以及粘度随磁场的变化情况。

| Abstract: | The effect of amount of emulsifier on the seeded emulsion polymerization was given in detail.Copolymer nanospheres of styrene/acrylic acid were prepared.In addition,the preparation of copolymer core magnetite shell composite particles were, reported.These composite particles were characterized by XRD and TEM.In this paper,a suspension with these composite particles dispersed was also prepared.Its suspension properties and viscosity variation with the applied magnetic field were further studied. |
