As references, conventional surfactant sodium dodecylsulfate or the mixture of surfactants sodium dodecylsulfate and nonylphenol polyoxyethylene ether (10) is used in the same polymer systems. Large amount of coagulum is producted during the polymerization, when the polymerizable surfactant from series A is used.

传统乳化剂十二烷基硫酸钠或十二烷基硫酸钠与壬基酚聚氧乙烯醚(10)(NP-10)复配的乳化剂也同样用于聚合以作对比。A系列乳化剂产品产生了大量凝胶，不适宜用于本文研究的乳液聚合中。

When the sodium lauryl sulfate and p-octyl polyethylene glycol phenyl ether is used and its level in 3% and 6: 4 ratio, the polymerization process has the lowest coagulum and the highest monomer conversion. Higher reaction temperature and more level hydroxyl value lead to more coagulum, the latter also lead to larger particle size. The acid value has larger influence on viscosity and coagulum, there exist a best range. The emulsion particle size is larger for its hydrophilicity, most of its particles are connected together.

在含较高亲水单体的乳液聚合体系中，难以制得稳定的预乳化液，不能采用工业生产中常用的预乳化工艺，而只能采用混合单体直接滴加的方法；由于单体混合物的亲水亲油值较高，用阴离子型乳化剂十二烷基硫酸钠和非离子型乳化剂聚乙二醇辛基苯基醚混合，用量为单体总量的3％，且比例在6：4时，乳液聚合时具有最低的凝聚物含量和最高的单体转化率；乳液聚合反应温度升高，可以提高单体转化率，增加反应速度，但凝聚率相应提高；随着羟基单体含量的增加，聚合过程中凝聚率增加，聚合物乳胶粒平均直径增加；羧基单体有一个最佳的用量（2.6％），过高或过低凝聚率均提高；羧基含量对乳液的粘度有较大的影响，当羧基含量较低时，羧基含量增加，乳液粘度增加明显；含羟基乳液粒子由于含亲水基团较多，使得乳胶粒径增大，乳胶粒子大多数互相凝聚在一起，处于凝聚态。

The differences of electric mechanism, phase behavior and high temperature stability of cyhalothrin drug-loading microemulsion were investigated when the dodecyl benzenesulfonic salts combined with five coherer counter-ions and polyoxyethylene styrenyl ether were mixed at the same molar ratio.
