摘要：

Micron PMMA microspheres which had PVP-g-PMMA graft polymers on the surface were prepared via a dispersion polymerization method by using the PVP K-30 as the dispersant. Because of the PVP-g-PMMA graft polymers, SiO2 nanoparticles were successfully introduced to the PMMA microsphere's surface through the TEOS hydrolysis method. SEM and other tests suggested micron-sized PMMA/SiO2 composite microspheres were successfully synthesized. SiO2 nanoparticles could grow on the PMMA microspheres, probably because SiO2 was attracted chemically to the carbonyl bonds on the PVP molecules.
