本文以过硫酸铵为引发剂,通过种子微乳液聚合的方法研究了阴离子型Gemini表面活性剂(自制)在形成涂料或胶粘剂用乳液的功能.研究发现阴离子型Gemini表面活性剂在微乳液聚合中是高效的乳化剂,可以提供典型的粒径控制及良好的乳液稳定性,只需1%左右就可以得到固含量45%左右的透明纳米级丙烯酸乳液,并维持平均粒径在31nm左右.

Function of Gemini emulsifiers (self-prepared) as anionic emulsifier in emulsion for coatings and adhesives is described by the process of seeded micro-emulsion polymerization initiated by the initiator ammonium persulfate (APS). It was found that Gemini emulsifiers are very effective in micro-emulsion polymerization, providing typical colloid particle size control, and excellent stability of the emulsion. With only about 1% content, high solid-content (about 40%) and small particle diameters (about 31nm) transparent copolymer latexes were attained.
