Abstract: Molecular imprinting technique(MIT) is a technique to produce molecular recognition polymer materials with high selectivity and affinity.Polymerization occurrs between monomers and cross linker around a template.After removing template polymer with molecular memory to the template is obtained.It has been used in the fields of analytical chemistry,catalysis and organic synthesis.In this study,the effects of template molecule,functuional monomer,cross linking agent,and solvent on the preparation of imprinting polymer were studied.By ultra-violet absorption spectroscopy mutulaction between template molecule and functional monomer was analyzed,and selection and combination mechanism of polymer was predicted.

Key words: molecular imprinting technique, template molecule, functuional monomer, synthetic polymer
