Latexes of poly(n‐butyl acrylate‐co‐methyl methacrylate) [P(BA‐co‐MMA)] filled with magnesium–aluminum layered double hydroxides (MgAl‐LDHs) are synthesized using miniemulsion polymerization. Three commercial LDHs organically modified with different types of anions are used as fillers (Perkalite F100S, Perkalite A100, and Perkalite AF50) and three different types of surfactants are tested to stabilize the miniemulsions including a cationic, an anionic, and a nonionic one. Stable LDH‐containing miniemulsions are prepared with a mixture of sodium dodecyl sulfate and Triton X‐405 and the polymerizable co‐stabilizer octadecyl acrylate. They are then polymerized to yield nanocomposite latexes. Depending on the type of LDH used, the presence of the inorganic material in the reaction medium affects the polymerization kinetics. X‐ray diffraction analysis of the resulting nanocomposite films suggests exfoliation of the inorganic material. The glass transition temperature of the nanocomposites is not affected by the LDHs and the decomposition temperature of the nanocomposites determined by thermogravimetric analysis is greater than that of the pure polymer.

有机改性层状双氢氧化物作为填充剂在微乳液聚合中制备聚合物纳米复合材料的评价

聚（丙烯酸正丁酯-共-甲基丙烯酸甲酯）[P（BA- co[-MMA）]填充有镁铝层状双氢氧化物（MgAl-LDHs），是使用细乳液聚合法合成的。将三种用不同类型的阴离子进行有机改性的商业LDH用作填充剂（Perkalite F100S，Perkalite A100和Perkalite AF50），并测试了三种不同类型的表面活性剂以稳定微乳液，包括阳离子，阴离子和非离子表面活性剂。用十二烷基硫酸钠和Triton X-405以及可聚合的共稳定剂丙烯酸十八烷基酯的混合物制备稳定的含LDH细乳液。然后将它们聚合以产生纳米复合乳胶。根据所用LDH的类型，反应介质中无机材料的存在会影响聚合动力学。所得纳米复合材料薄膜的X射线衍射分析表明，无机材料会脱落。纳米复合材料的玻璃化转变温度不受LDH的影响，并且通过热重分析确定的纳米复合材料的分解温度高于纯聚合物的分解温度。
