| 摘 要： | 使用可聚合乳化剂烯丙氧基壬基酚丙醇聚氧乙烯（10）醚硫酸铵（DNS-86），通过半连续聚合工艺制备了水基丙烯酸酯乳液。考查了DNS-86对乳液的固含量、转化率、乳胶粒的大小及形态、Zeta电位以及各种稳定性（聚合稳定性、化学稳定性及冻融稳定性）的影响。与常规乳化剂十二烷基硫酸钠（SDS）制备的丙烯酸酯乳液性能进行了对比。结果表明，DNS－86因反应活性大，能与丙烯酸酯单体进行共聚，制得的乳胶粒大小均一，形态规整，乳液的稳定性得到改善。

| Abstract: | In this paper, the acrylate emulsions were systhesized by dropwise manner of monomers using the emulsifier allyloxy nonylphenol propyl polyoxyethylene （10） ether sulfate （DNS-86）, and then their properties were compared with the emulsions prepared with conventional emulsifier sodium dodecyl sulfate （SDS）. The effects of emulsifier DNS-86 on the solid content, conversion of monomers stability, size and morphology of emulsion particles and Zeta potential were investigated. The reason of affecting the stability of emulsion for polymerizable emulsifier DNS-86 was explored. The results showed that compared with the conventional emulsifier SDS, the emulsion stability is improved when the emulsifier DNS-86 is used. |
