Abstract
AbstractCalcium carbonate (CaCO3)/poly(methyl methacrylate) (PMMA) composite microspheres were synthesized in a soapless emulsion polymerization process. CaCO3 nanoparticles were pretreated with oleic acid to improve the compatibility between CaCO3 and the monomer methyl methacrylate, and this effectively enhanced the mass fraction of CaCO3 in the composite. The results of the thermogravimetric analysis showed that the thermal stability of the composite microspheres was better than that of PMMA. X‐ray diffraction and Fourier transform infrared were applied to investigate the chemical and physical properties of the composite microspheres, and the results proved that the composites were composed of CaCO3 and PMMA. Scanning electron microscopy and transmission electron microscopy pictures showed that the morphology of the composite microspheres was uniform, and the CaCO3 nanoparticles could be well dispersed in the polymeric matrix. The soapless emulsion polymerization process effectively increased the filling amount of CaCO3 in the composite microspheres. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
