More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.
无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点,首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合,发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大,具有单分散性;较多的纳米粒子导致较大的乳液粒径;反应温度升高,凝聚物含量下降,而乳液粘度和乳胶粒粒径增加,在相同的反应温度下,纳米粒子降低了聚合过程中的凝聚物含量,增加了乳液聚合物的粘度和粒径;不论纳米粒子是否存在,当无皂乳液核组成中亲水单体AA和HEMA用量增加时,乳胶粒粒径均减少。

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。
