Molecularly imprinted polymers(MIPs)using p-hydroxybenzoic acid(p-HB)as template,4-vinylpyridine(4-VP),acrylamide(AM)and α-methylacrylic acid(MAA)as functional monomers were prepared separately. First,the binding energy of p-HB with the above monomers is calculated by using the molecular mechanics method. The order of binding energy of p-HB with different monomers is 4-VP>AM>MAA. Second,the interaction strength between p-HB and different monomers is studied by UV analysis, which is in the same order(4-VP>AM>MAA).Third, the static adsorption experiments of the MIPs using 4-VP,AM or MAA as functional monomer show that the binding capacity order of these MIPs is also 4-VP>AM>MAA,the same with those from molecular mechanics calculation and UV analysis. The results demonstrate that 4-VP is the best among the three monomers对羟基苯甲酸
