摘要: 合成了一种新型可共聚单体烯烃基甘油醚磺酸盐(AGES),不仅含有具有反应活性的烯键,而且带有起乳化作用的磺酸离子基团及羟基,可用于MMA/BA无皂乳液聚合体系。对乳胶粒大小、乳液的流体力学行为及共聚物的动态力学性能进行了研究。实验结果表明:通过AGES的引入,可获得直径为0.5μm左右的分布均匀的乳胶粒,乳液含固量高(60%),粘度低,是稳定的塑性非牛顿流体乳液,共聚物为典型的无规共聚。

Abstract: In this article, allylglycerdyl ether sulfosalt(AGES), a novel copolymerizable monomer containing not only the reactive vinyl bond, but also groups of sulforous and hydroxyl having the role of emulsifier was synthesized and used in the MMA/BA emulsifier-free emulsion polymerization. Particle size and flowing behavior of the latexes, as well as dynamic mechanical properties of the resulted copolymers were investigated. The results show that with the addition of AGES, the latex particles are about 0.5 μm in diameter and are evenly distributed; stable latexes of high solid content(60%), low viscosity with the characteristic of plastic Non-New ton flowing behavior is obtained. In addition, all the polymerization systems undergo a typical random copolymerization.
