阳离子可聚合表面活性剂的研究进展

可聚合表面活性剂含有可聚合基团,以牢固的共价键键合到聚合物粒子上,成为聚合物的一部分,有效避免了表面活性剂的解吸及其在乳胶膜中的迁移,减少了乳胶膜表面的亲水基团,可以克服传统表面活性剂的许多弊端。阳离子可聚合表面活性剂主要为季铵盐,其容易吸附于一般固体表面,其水溶液一般有优异的杀菌性。本文综述阳离子可聚合表面活性剂,根据不同方式对其进行分类,分别介绍聚合基团不同的阳离子可聚合表面活性剂的合成和应用现状,并对其应用前景作了展望。

Cationic Advances in Polymerizable Surfactant

Polymerizable surfactants contain polymerzable group,which,as part of the polymer,ensures 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 and reduce the water group of the latex surface.Polymerizable surfactants can overcome many drawbacks of traditional surfactants.Most cationic polymerization surfactants are quaternary ammonium salt,which are easy to be absorbed on surface of solids and whose aqueous solution has excellent bactericidal activity generally.This article summarizes cationic polymerization surfactants which are classified by different methods,and introduces the synthesis and current application of cationic polymerization surfactant based on the difference of polymer groups,and their prospective application is also described.
