Abstract: In this paper, the functional polymer microspheres with epoxy functional groups on the surface were prepared by using a self-made continuous photopolymerization device based on suspension photopolymerization. Polymeric PGMA microspheres were prepared by copolymerization of glycidyl methacrylate (GMA) with divinylbenzene (DVB). The effects of initiator dosage, monomer ratio, solvent ratio, stirring rate and light intensity on microsphere size and morphology were investigated. The structure, morphology and properties of the samples were characterized by electron microscopy, infrared spectroscopy (IR) and thermogravimetric (TG). By optimizing the experimental conditions, the particle size controllability of the microspheres was realized. IR determined that the microspheres contained epoxy group, and the microspheres prepared by the microscope had a good sphericity. These results showed the surface of the microscope is rich in epoxy and easy to be modified.
