## Abstract Calcium carbonate (CaCO~3~)/poly(methyl methacrylate) (PMMA) composite microspheres were synthesized in a soapless emulsion polymerization process. CaCO~3~ nanoparticles were pretreated with oleic acid to improve the compatibility between CaCO~3~ and the monomer methyl methacrylate, and
## Abstract Poly(methyl methacrylate) (PMMA)/Titanium oxide (TiO~2~) composite particles were prepared via __inβsitu__ emulsion polymerization of MMA in the presence of TiO~2~ particles. Before polymerization, the TiO~2~ particles was modified by the silane coupling agent, which is crucial to ensur
Nanozirconia (nano-ZrO 2 ) was prepared by the sol-gel method and incorporated into poly(methyl methacrylate) (PMMA) by the in situ bulk polymerization of methyl methacrylate. The structure of the nano-ZrO 2 was confirmed by X-ray diffraction (XRD), transmission electron microscopy, and Fourier tran
