摘　　要：采用半连续乳液聚合的方法,合成聚醋酸乙烯乳液,探讨乳化剂的种类,配比及浓度对乳液聚合稳定性和粘度的影响。该乳液稳定性能良好,木-木压缩剪切强度达12MPa以上,可作为多孔性物质的胶粘剂使用。Polyvinyl acetate emulsion was prepared with semi-continuous emulsion polymerization. The experiments show that different emulsifiers, the concentration of emulsifiers and the ratio of emulsifiers have great effects on polymerization stability and viscosity of emulsion. The compression shear strength of emulsion is above 12MPa and it can be used as adhesive for porous materials.
