ABS/silicate composites with different clay types and compositions were prepared by in situ emulsion polymerization. The chemical structure of ABS was confirmed by the change of C-H stretching peak(near 3000 $cm^{-1}$) in fourier transform-infrared(FT-IR) spectrum. The thermal properties of the ABS/silicate composites were investigated by differential scanning calorimetry(DSC) and thermogravimetric analyzer(TGA). There was no distinct change in glass transition temperature of the ABS/silicate composites with different clay types. TGA curve indicates a dramatic increase in degradation temperature in case of ABS/20A composite with 3 wt% 20A. The silicate dispersion in the composites was measured by X-ray diffraction(XRD). The silicate dispersion in ABS/20A composites depended on the 20A composition. XRD results showed that the diffraction peak of the ABS/20A composite appeared when the content of 20A was higher than 5 wt%.
