Abstract: Three molecularly imprinted polymers were synthesized with different functional monomers respectively, using methyl parathion as the template. These monomers are methacrylic acid, acrylamide and 4-vinylpyridine. According to the UV spectrum study the interaction between methyl parathion and 4-vinylpyridine was stronger than that of the others. Comparably, the infrared spectrum study showed the same results which indicated that 4-vinylpyridine could associate with the template at two different kinds of binding sites, the P-O-C and the -NO2 site, and is most likely to form steady covalent bonds with methyl parathion, while the other two monomers could only associate with the template at the P-O-C site. Furthermore, the infrared spectra of the synthesized polymers confirmed the existence of the functional groups in each kind of polymer, which might interact with the template
