摘要： 采用PVA和DBS-Na复合分散剂,在高速搅拌下(1500～2000转/min),用悬浮聚合法合成了粒度分布较窄的聚合物微球(3～10μm),并考查了聚合反应条件对聚合微球粒度及其分布的影响。最后,对所得磺化微球在氨基酸分析方面的应用进行了试验。

Abstract: The narrow distributed polymeric microparticles with diameters of,3-10 μm were prepared by suspension polymerization when PVA and DBS-Na were used as the mixed dispersant with the rate of stirring 1500-2000 r/min. The effects of the conditions of the polymekrization reactions on the diameters and their distributions of the microparticles were examined. Thereafter, the authors studied the properties of the sulfonated polymeric microparticles which were used as the stationary phases of an amino acid analyzer.
