Poly(methyl methacrylate) and poly(butyl acrylate) lattices have been synthesized under ultrasonic irradiation in the presence of a cationic surfactant, dodecyltrimethylammonium chloride. The polymerization of oil-in-water emulsions of monomeric species was carried out at 30 degrees C (+/-5 degrees C) in the absence of a chemical initiator. The lattices were formed as stable dispersions with particle diameters spanning the range of 40-150 nm and with polymer molecular weights greater than 10(6) g mol(-1). The results obtained strongly support a polymerization process involving a miniemulsion system, in which continuous nucleation of particles takes place throughout the monomer to polymer conversion reaction.
聚（甲基丙烯酸甲酯）和聚（丙烯酸丁酯）胶乳是在阳离子表面活性剂十二烷基三甲基氯化铵存在下，通过超声辐照合成的。单体种类的水包油乳液聚合在30℃（±5℃）下进行，无需化学引发剂。形成的胶乳为稳定分散体，粒径范围为40-150nm，聚合物分子量大于10⁶ g mol⁻¹。所得结果有力地支持了一种涉及细乳液体系的聚合过程，即在单体到聚合物的转化反应过程中，颗粒持续成核。
