摘要
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.
