摘要：

A method for synthesizing magnetic polymer microspheres with carboxyl groups on the surface is proposed. In an aqueous medium, magnetic microspheres form stable colloidal dispersions with an average hydrodynamic particle diameter of 110-170 nm and a negative surface charge. When dispersed in an aqueous-organic mixture, the microspheres remain resistant to aggregation. Microspheres can be extracted from the dispersion using an external magnetic field. Magnetic microspheres can be used as supports for heterogeneous catalysts operating in organic media.
