摘　　要：笔者通过乳液聚合法首先制备聚苯乙烯(PS)微球,再以此作为种球,以快杀稗为模板分子,加入溶剂、功能单体、交联剂等试剂成功地通过单步溶胀聚合法得到了分子印迹聚合物(MIPs)。再对制备MIPs的结构进行了分析和表征,通过紫外分光光度计测定不同浓度快杀稗分子的N,N-二甲基甲酰胺溶液的吸收值,并以此绘制标准曲线,再结合等温线分析MIPs的底物结合能力,发现其具有高负载量和高效的识别性,然后用扫描电镜观察了微球的形貌,其结果显示,MIPs具有良好的球形结构,粒径在200—500 nm,并且球的表面具有大量一定孔径分布的致密孔穴。Polystyrene（PS） microspheres were prepared by emulsion polymerization, regard it as a ball, Quinclorac as template molecule, put functional monomer,crosslinking agent and the other reagents succeeded in passing the single-step swelling polymerization molecularly imprinted polymers （MIPs） are obtained. To the structure of the preparation of MIPs are analyzed and characterization, again impassability concentration can be determined through ultraviolet spectrophotometer quinclorac of N, N - dimethyl formamide solution absorption value, and drawing standard curve, combined with isotherm analysis of MIPs substrate binding ability, found that the identification of the high load and high efficiency, and then the morphology of the microspheres is observed by scan electron microscope, the results showed that MIPs have good spherical structure, particle size in 200-500 nm, and the ball surface has a large number of certain pore size distribution of the density cavity.
