Nanocomposite of ABS (acrylonitrile-butadiene-styrene copolymer) resin and clay was prepared by melt compounding using a twin screw extruder. The state of dispersion and microstructure in ABS resin/clay nanocomposite were observed by XRD. The mechanical and thermal properties of nanocomposite were also investigated. When ABS resin was intercalated to the silicate layer in clay, the separation distance between the layers increased by 1.7 nm. In the nanocomposite studied here, both tensile and flexural strength were hardly improved and Izod impact was severely deteriorated. However, modulus and heat distortion temperature were improved. The reduction of modulus above Tg was observed by the dynamic viscoelasticity measurement.
