Abstract：PEG-modified Fe3O4/PVA magnetic polymer micropheres were synthesized and characterized by microphotography, laser diffraction particle analysis, FT-IR spectroscopy etc. The results indicate that the size of micropheres presents a Gaussian distribution, and PEG could be immobilized to PVA magnetic microspheres. The magnetic polymer microspheres are stable in a wide range of pH and temperature. The contents of PEG and Fe3O4 were about 190 mg/g and 100 mg/g in the microspheres respectively. These properties make the microspheres promising in applications in the field of catalysis and biotechnology.
