Molecularly imprinted polymers （MIPs）, using （S）-naproxen as template and the combination of butyl methacrylate （BMA） and MAA （1：1 molar ratio） as functional monomers were synthesized by an in situ polymerization reaction. The rendered monolithic column was evaluated in HPLC mode. The result showed that the monolithic MIPs with the combination of two monomers produced better chiral resolution of rac-naproxen （Rs = 1.55） and column efficiencies of imprinted molecules （N = 2860 plates/m） than that with pure MAA.
