摘要
在乳液聚合中,表面活性剂发挥着非常关键的作用,但同时它们也存在不足的方面,一个比较有前景的方法就是使用可聚合表面活性剂。可聚合表面活性剂以牢固的共价键键合到聚合物粒子上,有效避免了表面活性剂的解析及其在膜中的迁移。本文综述了近年来可聚合表面活性剂的进展,主要讨论了阴离子、非离子、阳离子可聚合表面活性剂的特征和性质及其在乳液聚合中的应用。
Surfactants play a crucial role in the emulsion polymerization. However, they also have some adverse effects. A promising way to reduce the negative effects of the surfactants is to use polymerizable surfactants. Application of polymerizable surfactants ensures that the surfactant moiety is bound covalently to the polymer material so that desorption from the polymer particles or migration in the polymer film are impeded. This text concludes the characterization and properties of anionic, noionic, cationic polymerizable surfactants and their applications in emulsion polymerization.
