Abstract: Molecularly imprinted polymeric microspheres(MIPMs) was prepared by suspension polymerization using methacrylic acid as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the cross-linking and 2,4-dichlorophenoxyacetic acid (2,4-D) as template molecule. The polymerization formula was optimized by orthogonal experiment and UV method was used to study the performance of the polymers. The results showed that MIPMs have better adsorption properties and select properties compare to references．

Key words: 4-dichlorophenoxyacetic acid, suspension polymerization, molecularly imprinted polymeric microspheres
