The encapsulated TiO〓 particles by polymer were obtained with soapless emulsion polymerization of methyl methacrylate in water in the presence of the pretreated TiO〓 particles.

一种是用偶联剂钛酸丁酯对亲水性TiO〓粒子进行预处理，钛酸丁酯与TiO〓表面羟基反应，交联到TiO〓粒子表面，使TiO〓粒子表面由亲水性转变为憎水性，改善无机粉体与有机单体的亲合性，再进行TiO〓存在下甲基丙烯酸甲酯的无皂乳液聚合，即可得到TiO〓-PMMA复合粒子：另一种方法是用表面活性剂对TiO〓进行预处理，再进行TiO〓粒子存在下甲基丙烯酸甲酯的无皂乳液聚合，TiO〓粒子表面可形成一层均匀的聚合物膜，提出了包覆机理，指出单体在无机粉体表面发生聚合的关键是预先在粒子表面形成聚合场所，即吸附一层表面活性剂。

The fluorescent intensity ratio of the first vibronic peak (λ=373 nm) to the third vibronic peak (λ=383 nm) of pyrene solubilized in micelle decreased gradually, which was different from the conventional surfactant, such as SDS. The aberrant property indicated a broad micelle size for the m+nAr-T surfactants. That is, the aggregates of the studied surfactants gradually grew in size with increasing concentration over wide concentration range.

与传统表面活性剂不同，增溶于N-酰基牛磺酸钠胶团中的芘的第一个电子振动峰(λ=372nm)的荧光强度I1和第三个电子振动峰(λ=385nm)的荧光强度I3之比I1/I3值随着表面活性剂浓度的增加而缓慢降低，说明了N-酰基牛磺酸钠表面活性剂在低浓度区形成疏松的聚集体，随着浓度的增大则有更多的表面活性剂分子挤入已形成的聚集体。

The effects of various structure parameters of gemini surfactants such as nature of the hydrophilic head groups,nature and chain length of the hydrophobic tail groups,nature and chain length of the spacer groups,and nature of the counter ion et al.on their dissolution properties,surface activity,micelle morphology,foaming performance and lime soap dispersing power et al.were summarized.
