摘要： 超浓乳液聚合有着良好的应用前景[1,2].但文献报道的超浓乳液研究多集中于苯乙烯体系,而对于在此基础上引入功能基单体制备超浓乳液,研究得较少[3].本文研究了影响苯乙烯(St)与甲基丙烯酸(MAA)制备(St-MAA)超浓乳液稳定性的因素.探讨了其聚合方法.

关键词: 苯乙烯, 甲基丙烯酸, 超浓乳液, 稳定性, 乳液聚合

Abstract: The preparation of concentrated St-MAA emulsion by one step method is investigated. The stability of the emulsion is affected by the kinds and concentration of the emulsifiers, volume fraction and polarity of the monomer. The polymerization of concentrated St-MAA emulsion was carried out using azo-bis-isobutyronitrile as initiator. Results indicate that the average size and dispersity of the latex particles depend on the concentration of the surfacant and monomer fraction.

Key words: styrene, methylacrylic acid, concentrated emulsion, stability, emulsion polyme rization
