摘　　要：以苯乙烯、丙烯酸丁酯为混合单体,十二烷基硫酸钠和壬基酚聚氧乙烯醚为复合乳化剂,过硫酸钾和亚硫酸氢钠为氧化还原引发体系,进行乳液聚合制备苯乙烯-丙烯酸丁酯水性共聚乳液.用粒度测定、红外光谱和热分析等仪器对聚合乳液进行了表征.结果表明引入氧化还原体系合成苯丙乳液能在较低温度下引发进行,乳液聚合产物的性能较好.Styrene acrylic copolymer emulsion was prepared using styrene,butyl acrylate as a mixture of monomer,sodium dodecyl sulfate and nonylphenol ethoxylates as emulsifier,and potassium persulfate and sodium bisulfite for the oxidation reduction system.The emulsion was characterized by particle size analyzer、FT-IR and DSC.The experiment results showed that the emulsion can be proceeded more quickly in low temperature,and the properties of the emulsion were relatively good.
