Preparation of MIP microspheres by precipitation polymerization with 1-phenyl-1-propanol as template

Abstract

Molecular imprinting polymer microspheres were prepared by precipitation polymerization with methacrylic acid as functional monomer and 1-phenyl-1-propanol as template. The effects of synthesis conditions, including the kind of solvent, polymerization temperature, the concentration of template and initiator, rotational speed and pre-polymerization time, on the characteristics of the molecularly imprinted polymer microspheres were studied. The rebinding experiments showed that the molecularly imprinted polymer microspheres synthesized by precipitation polymerization at 60掳C, with acetonitrile as solvent and the concentrations of both template and initiator of 0.01mol L-1, have good specific recognition and higher affinity capacity.
