酸处理对制备中空乳胶粒子的影响
摘要:
从60年代起就开始了乳胶粒子形态控制方面的研究[1].随着人们对精细材料和新型聚合物要求的不断提高,空洞型结构的异形粒子引起了人们越来越大的兴趣[2~4].由于中空化乳胶粒子独特的优点,到90年代已成为一个广阔的新的研究领域.目前此方面的工作还处于开始阶段.

Effect of Acid Treatment on the Preparation of Hollow Latex Particles
Abstract:
The styrene(St)-butyl acrylate(BA) copolymer was first prepared as seed emulsion and the final latex of St-BA-MA was then obtained from it with methyl acrylate(MA). The hollow polymer particles were obtained from poly(St-BA-MA) in the presence of dodecyl sulfonic sodium through alkaline and acid treatments. In this paper the effects of pH value, temperature and time of acid treatment on the hollow structure of polymer particles were investigated. The results showed that the largest hollow size can be obtained when acid treatment conditions were: pH 2.5, 85℃ and 3 hours.
