    In order to obtain the best condition, bulk polymerization isfirstly carried on the study of the functional monomer, crosslinker,initiator andreaction conditions on the preparation and performance of MIPs by the single factorand orthogonal experiment, the superior condition is that Theα-Methyl Acrylic Acidis used as a functional monomer, Ethylene Glycol Dimethacrylate is used ascrosslinking agent, the ratio is 1:4:20, chloroform is used as a solvent,2,2'-Azobisisobutyronitrile is used as initiator, the amountis 60mg, reactivetemperature is 60℃, L-tyrosine molecularly imprinted polymers (MIPs) of goodadsorption properties can be produced, the extraction efficiencies is as high as 86.57%,saturation adsorption is as high as 77.66μmol/g. Then molecularly imprinted polymer in the aqueous suspension system iscomparatively studied, its optimal reaction conditions: Mixing speed is 200r/min, theratio of amount of substance among L-Tyr, MAA, EDMA is 1:4:20, the amount ofAIBN is 6.0g, 60℃water bathing,by this, L-tyrosine imprinted polymermicrospheres (MIMs)polymerization in relatively small average size (61μm) canbe produced.

    为了得到最优合成条件,首先采取本体聚合法制备L-酪氨酸分子印迹聚合物(MIPs),通过单因素实验和正交实验,研究了功能单体、交联剂、引发剂及反应条件对制备MIPs及其性能的影响,得出最优条件为:α-甲基丙烯酸(MAA)为功能单体,二甲基丙烯酸乙二醇酯(EDMA)为交联剂,其物质的量之比为1:4:20,以氯仿作为溶剂,偶氮二异丁腈(AIBN)作为引发剂,用为60mg时采用60℃加热聚合的方法,制备吸附性能良好的L-酪氨酸的印迹分子聚合物MIPs,其萃取效率高达86.57%,饱和吸附高达77.66μmol/g。
