Secondly,UV spectrophotometry was adopted to research the combination action on SM_2 and SIZ with MAA and 4-Vp.The combination action of functional monomer with template molecules were produced in the results. Then,the prediction imprinting principle of SM_2 and SIZ were given. The diagrams of infrared spectrum were analysed in MAA and 4-Vp and IMPs of SM_2. It was discoved that the absorbability peak of C=C function group in the IMPs were turn to be very low ,but the function group of carboxylic acid and pyridyl in the IMPs were no evidence change, and the condition was created in the molecular recognition of MIPs. Thermal Analysis was adopted to research IMPs ,in which ,a better thermal stability and its decompose temperature were showed in the results.
