Preparation of Ractopamine Molecularly Imprinted Polymer by Precipitation Polymerization

The molecularly imprinted polymer (MIP) of ractopamine was prepared by precipitation polymerization with ractopamine as template molecule, methacrylic acid as functional monomer, ethylene glycol dimethacrylate as cross-linker and azobisisobutyronitrile as initiator. It was found that the imprinted polymer had good affinity and specific selectivity for ractopamine.
