摘要： 合成了两种离子型表面活性单体(Surfmer)磺化-十二醇-烯丙基甘油-丁二酸酯钠盐(ZC-L)和磺化-十二醇-甲基丙烯酰甘油-丁二酸酯钠盐(ZD-L).着重研究了ZC-L的结构、表面张力行为、均聚及共聚能力.实验结果表明,不同Surfmer用量以及不同固含量下,MMA/BA/Surfmer,MMA/Surfmer及BA/Surfmer共聚乳液的表面张力较高,说明Surfmer已通过共聚结合在乳胶粒上,乳液中残留甚少.对MMA/BA体系,ZC-L的共聚性能比ZD-L好.

Abstract: Two surface active ionic monomers(surfmers)[sodium sulfonated lauryl(allyl glyceryl) succinate(ZC-L) and sodium sulfonated lauryl(methacryloyl glyceryl) succinate(ZD-L)] were synthesized and used in the emulsion copolymerization of methyl methacrylate(MMA) and butyl acrylate(BA). The investigation was emphasized particularly on ZC-L for its molecular structure, surface tension behavior and the reactivity for homo and copolymerization. The surface tensions of MMA/BA/Surfmer, MMA/Surfmer and BA/Surfmer copolymer latexes were remarkably higher than that of MMA/BA/sodium dodecyl benzene sulfonate copolymer latex, while similar to or higher than that of MMA/BAemulsifier-free copolymer latex, indicating that the surfmers were covalently bonded on polymer latex particles, and there is only a little remained in the aqueous solution. The ZC-Lcopolymerization reactivity with MMA/BA is better than that of ZD-L.
