马来酸类可聚合乳化剂及其在乳液聚合中应用

使用可聚合乳化剂可以很好地解决传统乳化剂的缺点,提高乳液的应用性能.马来酸类乳化剂其可聚合基团反应活性适中,可以很好地键合在乳胶粒表面上,且更为突出的是这类乳化剂不易发生均聚,而是倾向于与单体发生共聚.研究表明,马来酸类可聚合乳化剂应用到乳液聚合中,可以改善乳胶液的性能,提高乳胶膜的耐水性等.文章介绍了这一类新型的乳化剂,并根据其亲水基团进行了分类,分别介绍其合成路线,总结了马来酸类乳化剂的特点,概述了在常见乳液聚合体系中的应用与研究.

Maleic Polymerizable Emulsifier and Their Applications in Emulsion Polymerization

To use polymerizable emulsifier can solve the deficiency of traditional emulsifier and enhance the application functions of emulsion. The maleic emulsifier can make a firmer bond on latex surface because of its moderate reactivity. Furthermore, this kind of emulsifier can undergo copolymerization with comonomers, but cannot be homopolymerised. As a result, the application of maleic emulsifier in emulsion polymerization can meliorate the capability of emulsion along with water resistance of latex film. As a new type of emulsifier, Maleic polymerizable was introduced in the paper and it Was classified according to the different kinds of hydrophilic groups. Besides, the feature~ of maleic polymerizable emulsifier and various types of synthesis routes were summarized . Their applications in different polymerizable systems and progress were described as well.
