Abstract: Using a functional monomer (methyl methacrylate, acrylamide, ethyl acrylate and acrylic acid) and a crosslinker (glycol dimethyacrylate), molecularly imprinted polymers (MIPs) of dibenzoyl-L-tartaric acid (L-DBTA) with recognition properties were prepared by thermal polymerization method in the presence of a template (L-DBTA) in acetonitrile solution. The effects of different functional monomers, concentrations of functional monomers, cross-linker concentrations, polymerization temperatures, polymerization times, different solvents on the MIPs' recognition properties were discussed. The binding experiments and high-performance liquid chromatographic (HPLC) analysis of molecularly imprinted polymers (MIPs) of L-DBTA with recognition properties were conducted to evaluate the influences of various factors on DBTA binding. The experimental results indicate that the MIPs has higher L-DBTA binding ability than D-DBTA's and also higher than corresponding non-imprinted polymers. The binding ability is the highest at template (L-DBTA): functional monomer (MMA): crosslinker (GDMA) 1:4:20 (molar ratio) as polymerization temperature is 60 C and polymerization time is 48 h. Based on the optimal experimental results, the highest separation factor (α) of L-DBTA/D-DBTA of the MIPs can be 2.79
