摘　　要：以初始质量分数为21.4%的氯甲基苯乙烯,在十二烷基苯磺酸钠(LAS)聚/醚复配乳液体系中制备了粒径为65.0nm,单分散性良好的聚氯甲基苯乙烯纳米微球。用红外光谱仪、透射电子显微镜、Zeta电位粒度仪测试技术对产物的化学结构、粒径大小、形貌、单分散性进行了表征。结果表明,在复配乳液体系中可以在提高单体含量的同时,保持产物的粒径在纳米级,同时体系的稳定性良好。透射电子显微照片显示,制得的纳米微球之间存在黏连。并提出了氯甲基的存在可能是产生这种现象的原因。Poly （chloromethylstyrene） nanoparticles with diameters of 65.0 nm were prepared from chloromethystyrene in a mixture emulsion of LAS and polyether. The chemical composition was identified by IR and the particle size and size distribution were measured by Zetaplus and TEM. Results showed that the polymer content in the mixture emulsion system can be improved greatly, and the diameter of the product can be controlled in nanometer scale. The system was very stable. TEM result showed synechia occured among resulting nano-spheres, which was attributed to the chloromethyl on the benzene ring.
