The method of surface grafting of molecularly imprinted polymer on the spherical resin with the living radical polymerization was studied. The surface of poly-styrene-co-divinylbenzene resin was grafted with iniferter (initiator-transfer-terminator agent). Under the radiation of UV light, using (－)-ephedrine as the template, methacrylic acid as functional monomer, molecularly imprinted polymer was grafted on the surface of the resin. The influence of the synthetic conditions on the property of the material was investigated. The re-binding experimental result showed that the imprinted polymer grafted resin has affinity and selectivity for the template molecule. The recognition resulted from the imprinting process.

Key words: surface grafting of molecularly imprinted polymer, iniferter, micro-spherical poly-St-DVB resin, (－)-ephedrine
