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。

However, most of these amphiphilic copolymers are composed of hydrophobic main chain and hydrophilic side chains.

但是，就目前的两亲性接枝共聚物而言，其主链大部分是由憎水链组成的，而支链则由亲水链组成。

In order to resolve the repeatability of contact angle measurement, the factors such as droplet volume, measure time, hydrophilic and hydrophobic targets were studied by using deionized water on glass and paraffin surface.

针对喷雾液滴在靶标上接触角测量的重现性不佳等问题，以玻璃和石蜡模拟靶标表面，研究了去离子水在亲水和疏水靶标表面上液滴体积和测量时间对接触角测量的影响，结果表明：液滴体积越大接触角越小，这种趋势在亲水表面比疏水表面上更突出，测量时体积可分别选择在0.5~1μl和1~5μl；液滴滴下30-50s后与固体表面基本达到平衡，对接触角测量的准确度影响较小。

Its hydrophilic groups is the inside carbonyl and amine base, and its lipophilic groups is the inside hydrocarbon chain and outer methyl. PAMAM of integral generation basically has not the surface activity. Its reason is that its outer groups is acylamino groups having very strong hydrophilicity so as not to reduce the surface tension of water. PAMAM different from traditional surfactant, have not critical micelle concentration, and exist in the form of "unimolecule micelle" in water.

结果表明：半代的PAMAM水溶液的表面活性与其分子具有两亲结构有关，亲水基团是内部的羰基和胺基，亲油基团是内部的碳氢链和外层的甲基；整代的PAMAM水溶液基本上没有表面活性，其原因是其最外层基团是酰胺基，亲水性很强，不能降低水的表面张力；树状大分子与传统的表面活性剂不同，不存在临界胶束浓度，在水中是以&单分子胶束&形式存在。

Gemini surfactants is especial structure surfactants which have two hydrophile groups and two hydrophobic groups, and traditional surfactants only have one hydrophile group and one hydrophobic group, Gemini surfactants have better and higher surface activity.

Hydrophobic-hydrophilic macroporous polydivinylbenzene/polyacrylethylenediamine interpenetrating polymer networks (PDVB/PAEM IPN) were prepared by the sequential suspension polymerization method. These were composed of two networks, of which one was hydrophobic and the other was hydrophilic. The objective of this work was to study the adsorption thermodynamics and adsorption kinetics of this hydrophobic- hydrophilic IPN. The focus was on adsorption isotherms of vanillin at different temperatures, and these fit well into the Freundlich adsorption isotherm. The isosteric adsorption enthalpy, adsorption Gibbs free energies and the adsorption entropy could be calculated according to thermodynamic functions.
