简要研究了在磁流体存在下苯乙烯和甲基丙烯酸甲酯的乳液聚合。通过TG-DTA分析研究了所得乳胶粒子的热性能。在热分析后测定残留物的重量，表明有机组分完全分解，被认为是一种简便实用的方法来确定胶乳颗粒中的磁铁矿含量。该方法被应用到磁性聚苯乙烯乳胶粒子的存在下制备的各种量的铁磁流体。结果分析表明，胶乳颗粒中的磁性含量主要由铁磁流体与单体的重量比决定。John Wiley & Sons，Inc.
Emulsion polymerization of styrene and methyl methacrylate in the presence of a ferrofluid was briefly studied. Thermal properties of the resulted latex particles were investigated by TG–DTA analysis. Determination of the residue weight after the thermal analysis that indicated complete decomposition of the organic components was found to be a facile and practical method to determine the magnetite content in the latex particles. The method was applied to magnetic polystyrene latex particles prepared in the presence of various amounts of the ferrofluid. Analysis of the results suggested that the magnetic content in the latex particles is primarily determined by the weight ratio of the ferrofluid to monomer. © 1993 John Wiley & Sons, Inc.
