摘　　要：用甲基丙烯酸甲酯、丙烯酸丁酯及丙烯酸-2-羟丙酯作主单体,丙烯酸作功能单体合成了水性涂料用纯丙乳液,比较了常规乳化剂和可聚合乳化剂对丙烯酸酯乳液性能(包括聚合稳定性,化学稳定性等)的影响,同时用透射电镜观察了粒子形态。结果表明:使用可聚合乳化剂烯丙氧基壬基酚聚氧乙烯(10)醚硫酸铵(DNS-86),能有效改善乳液的性能。A pure acrylic emulsion for waterborne coatings has been prepared based on monomers of methyl methacrylate, butyl acrylate, 2 - hydroxy propylacrylate and acrylic acid. The influence of conventional emulsifiers and polymerizable emulsifiers on emulsion properties （including polymerization stability, chemical stability, etc. ） were compared. And the morphology of emulsions are characterized by TEM. It is found that the polymerizable emulsifier ammonium allyloxtmethylate nonylphenol ethoxylates sulfate （DNS - 86） can effectively improve the properties of emulsion.
